Introduction to Computational Fluid Dynamics What is Computational Fluid Dynamics? Computational Fluid Dynamics (CFD) is a computer-based tool for simulating the behaviour of systems involving fluid flow, heat transfer and other related physical processes. It works by solving the equations of fluid flow (in a special form) over a region of interest, with specified (known) conditions on the boundary of that region.

The History of CFD Computers have been used to solve fluid flow problems for many years. Numerous programs have been written to solve either specific problems, or specific classes of problem. From the mid-1970’s the complex mathematics required to generalise the algorithms began to be understood, and general purpose CFD solvers were developed. These began to appear in the early 1980’s and required what were then very powerful computers, as well as an in-depth knowledge of fluid dynamics, and large amounts of time to set up simulations. Consequently CFD was a tool used almost exclusively in research. Recent advances in computing power, together with powerful graphics and interactive 3-D manipulation of models mean that the process of creating a CFD model and analysing the results is much less labour-intensive, reducing the time and therefore the cost. Advanced solvers contain algorithms which enable robust solution of the flow field in a reasonable time. As a result of these factors, Computational Fluid Dynamics is now an established industrial design tool, helping to reduce design timescales and improving processes throughout the engineering world. CFD provides a cost-effective and accurate alternative to scale model testing, with variations on the simulation being performed quickly, offering obvious advantages.

The Mathematics of CFD The set of equations which describe the processes of momentum, heat and mass transfer are known as the Navier-Stokes equations. These are partial differential equations which were derived in the early nineteenth century. They have no known general analytical solution but can be discretised and solved numerically. Page 24

Introduction to Computational Fluid Dynamics

CFX-5.6

CFX-5 Reference Guide Introduction to CFD

Equations describing other processes, such as combustion, can also be solved in conjunction with the Navier-Stokes equations. Often, an approximating model is used to derive these additional equations, turbulence models being a particularly important example. There are a number of different solution methods which are used in CFD codes. The most common, and the one on which CFX-5 is based, is known as the finite volume technique. In this technique, the region of interest is divided into small subregions, called control volumes. The equations are discretised and solved iteratively for each control volume. As a result, an approximation of the value of each variable at specific points throughout the domain can be obtained. In this way, one derives a full picture of the behaviour of the flow. For full details on the Navier-Stokes equations and other mathematical aspects of the CFX-5 software suite see Basic Solver Capability Theory (p. 1 in Solver Theory).

Uses of CFD CFD is used by engineers and scientists in a wide range of fields. Typical applications include: • Process industry: Mixing vessels, chemical reactors • Building services: Ventilation of buildings, such as atria • Health and safety: Investigating the effects of fire and smoke • Motor industry: Combustion modelling, car aerodynamics • Electronics: Heat transfer within and around circuit boards • Environmental: Dispersion of pollutants in air or water • Power and energy: Optimisation of combustion processes • Medical: Blood flow through grafted blood vessels

CFD Methodology CFD may be used to determine the performance of a component at the design stage or it can be used to analyse difficulties with an existing component and lead to its improved design.

For example, the pressure drop through a component may be considered excessive:

The first step is to identify the region of interest:

The geometry of the region of interest is then defined. If the geometry already exists in CAD, it can be imported directly. The mesh is then created. After importing the mesh into the pre-processor, other elements of the simulation are then defined, including the boundary conditions (inlets, outlets etc.) and fluid properties.

Page 26

CFX-5 Reference Guide Introduction to CFD

The flow solver is then run to produce a file of results which contain the variation of velocity, pressure and any other variables throughout the region of interest. The results can be visualised and provide the engineer with a full understanding of the behaviour of the fluid throughout the region of interest.

This can lead to design modifications which can be tested by changing the geometry of the CFD model and seeing the effect. The process of performing a single CFD simulation is split into four components: Geometry/Mesh

Physics Definition

Solver

Post-processing

Geometry/Mesh This interactive process is the first pre-processing stage. Its aim is to produce a mesh for input to the physics pre-processor. Before a mesh can be produced, a closed geometric solid is required. The geometry and mesh can be created in CFX-Build or one of a variety of other geometry/mesh creation tools. The basic steps involve: • Defining the geometry of the region of interest. • Creating regions of fluid flow, solid regions and surface boundary names. • Setting properties for the mesh. This pre-processing stage is becoming increasingly automated. In CFX-5, geometry can be imported from most major CAD packages using native format, and the mesh of control volumes is generated automatically. CFX-5.6

CFX-5 Reference Guide Introduction to CFD

Physics Definition This interactive process is the second pre-processing stage and is used to create the input for the solver. The mesh files are loaded into the physics pre-processor, CFX-Pre, and then the following properties are defined: • The physical models which are to be included in the simulation are selected. • The properties of the fluid are specified. • The boundary conditions are specified. The Solver The solver is the component which solves the CFD problem, producing the required results. It is a non-interactive/batch process. It solves the CFD problem as follows: • The partial differential equations are integrated over all the control volumes in the region of interest. This is equivalent to applying a basic conservation law (e.g. for mass or momentum) to each control volume. • These integral equations are converted to a system of algebraic equations by generating a set of approximations for the terms in the integral equations. • The algebraic equations are solved iteratively. An iterative approach is required because of the non-linear nature of the equations and as the solution approaches the exact solution it is said to converge. For each iteration, an error, or residual, is reported as a measure of the overall conservation of the flow properties. How close the final solution is to the exact solution depends on a number of factors, including the size and shape of the control volumes and the size of the final residuals. Complex physical processes, such as combustion and turbulence are often modelled using empirical relationships, and the approximations inherent in these models also contribute to differences between the CFD solution and the real flow. The solution process requires no user interaction and is therefore usually carried out as a batch process. The solver produces a file of results which is then passed to the post-processor.

The Post-processor The post-processor is the component used to analyse, visualise and present the results interactively. Post-processing includes anything from obtaining point values to complex animated sequences. Examples of some important features of post-processors are: • Visualisation of the geometry and control volumes. • Vector plots showing the direction and magnitude of the flow. • Visualisation of the variation of scalar variables (variables which have only magnitude, not direction, such as temperature, pressure and speed) through the domain. • Quantitative numerical calculations. • Animation • Charts showing graphical plots of variables • Hardcopy output.

Introduction to CFX Expression Language (CEL) CEL is an interpreted, declarative language which has been developed to enable CFX-5 users to enhance their simulations without recourse to writing and linking separate external FORTRAN routines. You can use CEL expressions in CFX-Pre and CFX-Post anywhere a value is required for input. CEL can be used to: • Define material properties which depend on other variables. • Specify complex boundary conditions. • Add terms to the solved equations. You can also monitor the value of an expression during the solution using monitor points; see Monitor Points (p. 318 in CFX-Pre).

CEL Fundamentals How CEL Interacts with the CFX-5 Solver At various points in the flow solver operation, the calculation requires information such as the rate of flow at an inlet boundary, or the viscosity in some part of the fluid. This dependence can be specified in a simple manner, but more complex dependencies may be developed by using CEL. Consider the case of flow through a pipe. You may wish to set a velocity profile at the inlet which will typically be greatest at the centre. The profile can be expressed mathematically in terms of a function of x, y and z, which are CFX-5 System Variables known to the CFX-5 Solver. The mathematical definition of the profile is called an Expression, and the value of this expression is a Term which is input to the flow solver. You can define many terms in CFX-5 by way of expressions: fluid properties, subdomain sources, boundary conditions and initial values are all CFX-5 terms which can be described using expressions. A key feature of CEL is that it is used dynamically by the CFX-5 Solver. For example, you can set viscosity to be dependent on temperature using CEL, and the current heat transfer CFD solution will be computed for this relationship.

Values and Expressions CEL can be used to generate both Values and Expressions. Values are dimensional (i.e. with units) or dimensionless constants. The simplest type of definition is the dimensionless value, for example: b = 3 .743 You can also specify a value with units, for example: g = 9.81 [m s^-2] The dimensions of the quantities of interest for CFD calculations can be written in terms of mass, length, time, temperature and angle. The concept of units is fundamental to the behaviour of values and expressions. Values can be used directly, or they can be used as part of an Expression. For example, you can use an expression to add two values together: CFX-5.6

CEL Fundamentals

Page 11

CFX-5 Reference Guide CEL

<Expr_1> = + . In this example, you may wish to pre-define and , but this is not required. However, in order to add two quantities together, they must have the same dimension, i.e. it is meaningful to add a quantity in inches to one expressed in metres, but it is not meaningful to add one expressed in kilograms to one in square feet. Expressions can also be functions of other (pre-defined) expressions: <Expr_2> = <Expr_1> + Units follow the conventions in the rest of CFX-5, in that a calculation has a set of solution units (by default, SI units), and that any quantity can be defined either in terms of the solution units, or any other set of units with the correct form. An expression does not have its own units string, but if it references quantities which have dimensions, these will determine the resulting units for the expression. For example, if an expression depends inversely on the square of the x coordinate, then it has implied dimensions of length to the power -2.

CFX Expression Language Statements The CFX Expression Language is declarative. You declare the name and definition of the expression (and an optional comment or description) using expression language statements. The statements must conform to a predefined syntax which is similar to FORTRAN mathematical statements. The statement must consist of the following: • a number, optionally with associated units. This defines a constant. Constants without units are termed dimensionless. • one or more references to constants, system variables, or existing user variables, separated by + (addition), - (subtraction), * (multiplication), / (division) and ^ (exponentiation), with optional grouping of these by parentheses. The syntax rules for these expressions are the same as those for conventional arithmetic.

CFX-5.6

CFX-5 Reference Guide CEL

Use of Constants Constants do not need to be defined prior to being used in an expression. For example, you could choose to evaluate the expression x + 5 [m]. Or, you could define a constant, b = 5 [m] and then create an expression x + b. The use of constants may be of benefit in generating complicated expressions or if you have several expressions that use the same constants. Expression Syntax All numbers are treated as real numbers. The precedence of operators is as follows (from highest to lowest): • The unary minus or negation operator ‘-’ as in ‘-x’. • The power operator ‘^’ as in ‘x^y’. • Multiplication and division as in ‘x*y/z’. • Addition and subtraction as in ‘x+y-z’. Note a difference from FORTRAN is that in FORTRAN, if A has the value 1, then -A**2 is interpreted as -(A**2) and has the value -1. In CEL -A^2 is interpreted as (-A)^2 and has the value 1. For clarity, you can always use brackets to specify the order of operations. Multiple-Line Expressions It is often useful, particularly with complex expressions, to use more than one line when creating your expression. CFX-5 allows you to use multiple lines to generate an expression, provided each line is separated by an appropriate operator. For example, you may have an equation, A + B/C, that consists of three complex terms, A, B, and C. In this case, you could use three lines to simplify creating the expression: A+ B /C Note that the operator may be used at the end of a line (A +) or at the beginning of a line (/ C). You do not need to enter the operator twice. Once the expression has been created, it will appear in the Existing Definitions listbox as if it was generated on a single line (A + B/C). CFX-5.6

System Variable Prefixes In order to distinguish system variables of the different components and fluids in your CFX-5 model, prefixes are used. For example, if carbon dioxide is a material used in the fluid air, then some of the system variables that you might expect to see are:

air.density - the density of air air.viscosity - the viscosity of air air.carbondioxide.mf - the mass fraction of carbon dioxide in air In a single phase simulation the fluid prefix may be omitted, however for multiphase cases you must include the fluid prefix to distinguish between different fluids. CEL Variables “r” and “theta” r is defined as the normal distance from the third axis with respect to the Reference Coordinate Frame. theta is defined as the angular rotation about the third axis with respect to the Reference Coordinate Frame. Note: theta is expressed in Radians and will have values between -π and π. CFX-5.6

CEL Variable “rNoDim” rNoDim is a dimensionless system variable which can be useful for rotating machinery applications. It is a ratio of radii, defined to be zero at the minimum radius and unity at the maximum radius, so that in general: R – R min rNoDim = ----------------------------R max – R min where R is the radius of any point in the Domain from the axis of rotation. rNoDim is only available for Domains defined with a rotating frame of reference. CEL Variable “subdomain” subdomain is essentially a step function variable, defined to be unity within a Subdomain and zero elsewhere. This is useful for describing different initial values or fluid properties in different regions of the Domain. It works in all subdomains, and cannot be applied to specific subdomains (e.g. an expression for temperature in a subdomain could be 373*subdomain [K]). CEL Variables “atstep”, “ctstep”, “aitern” and “citern” These variables allow access to timestep and iteration number in CEL expressions. They may be useful in setting parameters such as the Physical Timescale via CEL expressions. Page 18

CFX-5 Reference Guide CEL

Steady-State Runs In steady-state runs, only aitern and citern are of use. citern gives the timestep number of the current run. The timestep number begins at 1 for each run, irrespective of whether it is a restarted run. aitern gives the accumulated timestep number, which accumulates across multiple restarted run. atstep is equivalent to aitern in a steady-state run and ctstep is equivalent to citern. Transient Runs In transient runs, atstep and ctstep are used for the accumulated and current timestep numbers of the outer timestep loop. citern gives the current timestep number of the inner coefficient loop within each timestep. Thus, citern will cycle between 1 and n for each timestep during a transient run, where n is the number of coefficient loops. aitern is of no use in a transient run, but if used is equivalent to citern. Expression names Your CEL expression name can be any name that does not conflict with the name of a CFX-5 system variable, mathematical function, or an existing CEL expression. See The RULES and VARIABLES Files (p. 87 in CFX-5 Solver Manager) for further details on viewing reserved names. Scalar expressions A scalar expression is a real valued expression using pre-defined variables, user variables and literal constants (e.g. 1.0). Note that literal constants have to be of the same dimension. Scalar expressions can include the operators + - * / and ^ and several of the mathematical functions found in standard FORTRAN (e.g. sin() and exp()). An expression’s value is a real value and has specified dimensions (except where it is dimensionless - but this is also a valid dimension setting). For example, if t is time and L is a length then the result of L/t has the same dimensions as speed. The + and - operators are only valid between expressions with the same dimensions and result in an expression of those dimensions.

CFX-5.6

CEL Variables, Functions and Constants

Page 19

CFX-5 Reference Guide CEL

The * and / operators combine the dimensions of their operands in the usual fashion. X^I, where I is an integer, results in an expression whose dimensions are those of X to the power I. The trigonometric functions all work in terms of an angle in radians and a dimensionless ratio. Expression properties There are three properties of expressions: • An expression is a simple expression if the only operations are +, -, *, / and there are no functions used in the expression. • An expression is a constant expression if all the numbers in the expression are explicit (i.e. they don’t depend on values from the solver). • An expression is an integer expression if all the numbers in the expression are integers and the result of each function or operation is an integer. For example (3+5)/2 is a simple, constant, integer expression. However, 2*(1/2) is not a constant integer expression, since the result of 1/2 is 0.5, not an integer. Also 3.*4 is not a constant integer expression, since 3. is not an integer. Moreover 2^3 is not a simple, constant, integer expression, since ^ is not in the list (+, -, *, /). Expressions are evaluated at runtime and in single precision floating point arithmetic. Available and Unavailable Variables CFX-5 System Variables and user-defined expressions will be available or unavailable depending on the simulation you are performing and the expressions you wish to create. In some circumstances, System Variables are logically unavailable; for instance, time (t) is not available for steady-state simulations. In others, the availability of a System Variable is not allowed for physical model reasons. For example, density can be a function of pressure (p), temperature (T) and location (x, y, z), but no other system variables. See The RULES and VARIABLES Files (p. 87 in CFX-5 Solver Manager) for information on how to find dependencies for all parameters. CFX-Pre checks expressions for syntax and use of system variables when you use them to define a parameter in CFX-Pre. Page 20

The expression definition can depend on any system variable. If, however, that expression depends on a system variable which is unavailable for a particular context, then that expression will also be unavailable.

Additional CFX-5 Solver CEL Functions CEL expressions can also incorporate specialised functions that are useful in CFD calculations. Table 4 (p. 24) summarises additional CEL functions that are available for use in CFX-Pre and the CFX-5 Solver. Important: The additional CEL functions and syntax documented here does not apply to use of CEL in CFX-Post. See Quantitative CEL Functions in CFX-Post (p. 200 in CFX-Post) for these details. The syntax used for calling these functions when used within CEL expressions is: [.]()@ where terms enclosed in square braces [ ] are optional and terms in < > should be replaced with the required entry. • [.] is optional and will default to all domain fluids if not specified. For multiphase results, it can be set to any single fluid in the domain by entering the fluid name followed by a period before the function definition. Table 4 (p. 24) lists the functions that accept this option. • specifies the CEL function to evaluate. Table 4 (p. 24) lists these functions. • () is the variable to be operated on. If this is not required (see Table 4 (p. 24)), it should be left blank (i.e. ()). You must use the short form for variable names, as listed in Table 1 (p. 14). You cannot use a general CEL expression, as in CFX-Post. You could create an Additional Variable based on an expression and then use the Additional Variable as the argument. The variable operated on is always the conservative variable. • @ should be a named boundary, domain or subdomain region that is defined in the CCL file. The valid regions for each function are listed in Table 4 (p. 24). An example of the calling syntax in an expression is: Pinitial = areaAve(p)@Inlet

which results in the area-weighted average of pressure on the boundary named Inlet.

The CEL variables x, y and z, representing the local coordinates, cannot be used as the variable. However, the variables xGlobal, yGlobal and zGlobal can be used (see Coordinate Frames (p. 24 in Solver Modelling)). For example, the following is a valid expression definition: z*areaAve(xGlobal)@inlet

Operations performed on a domain use vertex values. Operations on a subdomain use element values. By combining these functions with the monitor points feature, you can monitor the value of an expression which is based on these functions; see Monitor Points (p. 318 in CFX-Pre).

Using Expressions The interaction with CEL consists of two phases: • a definition phase, and, • a use phase. The definition phase consists of creating a set of values and expressions of valid syntax. The purpose of the Expression Editor is to help you to do this. Use of Offset Temperature When using temperature values in expressions it is generally safer to only use units of [K]. When units are used that posses an offset temperature scale are used (e.g. [C]), they are converted internally to [K]. When a term is specified with a simple temperature unit (to the power of unity), then any units conversion will include the offset between temperature scales. However, in all other cases the offset is ignored since this is usually the most appropriate behaviour. You should therefore take care when specifying an expression involving non-unit powers of temperature. For example, each of the expressions below is equivalent: Temperature Temperature Temperature Temperature

= = = =

30 [C] 303.15 [K] 0 [C] + 30 [K] 273.15 [K] + 30 [K]

These are only equivalent because all units are to the power of unity and units other than [K] appear no more than once in each expression. The following expression will not produce the expected result: Page 26

CEL Variables, Functions and Constants

CFX-5.6

CFX-5 Reference Guide CEL

Temperature = 0 [C] + 30 [C]

This is equivalent to 576.30 [K], since each value is converted to [K] and then summed. The two expression below are equivalent (as expected) because the offset in scales is ignored for non-unit powers of temperature: Specific Heat = 4200 [J kg^-1 C^-1] Specific Heat = 4200 [J kg^-1 K^-1]

CEL Examples In addition to the examples presented below, the following links to the CFX-5 Tutorials contain examples of creating CEL expressions in your model: • To create an expression for temperature dependent viscosity (p. 122 in CFX-5 Tutorials). • Expression Method for the Inlet Velocity Profile (p. 285 in CFX-5 Tutorials). • To create the expression for shear rate dependent viscosity (p. 343 in CFX-5 Tutorials).

Example 1: Reynolds Number Dependent Viscosity In this example it is assumed that some of the fluid properties, including the dynamic viscosity, are not known. However the Reynolds number, inlet velocity and a length scale are known. The flow is compressible and therefore the density is variable. Given this information it is possible to calculate the fluid dynamic viscosity based on the Reynolds number. The Reynolds number is given by: ρUL Re = ----------µ where ρ is density, U a velocity scale, L a length scale and µ the dynamic viscosity. The velocity scale is taken as the inlet velocity, the length scale as the inlet width and the density is calculated as the average density over the inlet area. The LIBRARY section of the CCL (CFX Command Language) file appears as follows: LIBRARY : CEL : EXPRESSIONS : Re = 4.29E6 [ ] Vel = 60 [m s^-1] L=1.044[m] Visc=areaAve(density)@in*Vel*L/Re END END MATERIAL : Air Ideal Gas Page 28

CEL Examples

CFX-5.6

CFX-5 Reference Guide CEL

Option = Pure Substance PROPERTIES : Option = Ideal Gas Molar Mass = 2.896E1 [kg kmol^-1] Dynamic Viscosity = Visc Specific Heat Capacity = 1.E3 [J kg^-1 K^-1] Thermal Conductivity = 2.52E-2 [W m^-1 K^-1] END END END

This shows that four CEL expressions have been created. The first three expressions define constant values that are used in the Visc expression. The Visc expression calculates the dynamic viscosity based on the equation for Reynolds number given above. Within the expression the function areaAve(density)@in is used to evaluate the average density at the inlet. This function can be selected in CFX-Pre in the Expression Editor, see Expression Editor (p. 150 in CFX-Pre). The Visc expression can now be used to replace the value of Dynamic Viscosity in the MATERIAL > PROPERTIES section.

Example 2: Feedback to Control Inlet Temperature In this example a feedback loop is used to control the outlet temperature by varying the temperature at an inlet. To illustrate the example consider the geometry shown below: Figure 2 Temperature feedback loop Side Inlet Temperature Control Inlet Flow = 5 m/s Flow = 1 m/s T = 375 K T = Tcontrol

Main Inlet Flow = 0.5 m/s T = 275 K

CFX-5.6

Outlet

CEL Examples

Page 29

CFX-5 Reference Guide CEL

Fluid from a main and a side inlet enter at temperatures of 275 K and 375 K respectively. The temperature of the fluid entering from the third inlet depend on the outlet temperature. When the outlet temperature is greater than 325 K, the fluid from the third inlet is set to 275 K. When the outlet temperature is less than 325 K, the fluid from the third inlet is set to 375 K. In addition an expression is used to set the dynamic viscosity to be a linear function of temperature. The LIBRARY section of the CCL (CFX Command Language) file appears as follows. Note that the the “\” character indicates a line continuation in CCL. LIBRARY: MATERIAL: Water at STP Modified Option = Pure Substance PROPERTIES: Option = General Fluid Density = 9.999E2 [kg m^-3] Dynamic Viscosity = VisT Specific Heat Capacity = 4.21E3 [J kg^-1 K^-1] Thermal Conductivity = 5.69E-1 [W m^-1 K^-1] END # PROPERTIES END # MATERIAL Water at STP Modified CEL: EXPRESSIONS: Tupper = 375.0 [ K ] # Upper temp.

Page 30

CEL Examples

CFX-5.6

CFX-5 Reference Guide CEL

The first four expressions, Tupper, Tlower, Visupper and Vislower are simply constant values to define temperature and viscosity values. The expression VisT produces a linear function for the dynamic viscosity taking a value of Visupper at Tupper and a value of Vislower at Tlower. The expression Tm sets the desired value of the outlet temperature. In this case it is set to a mean value of the two inlet temperatures. Tout calculates the outlet temperature using the areaAve function. This function can be selected in CFX-Pre in the Expression Editor, see Expression Editor (p. 150 in CFX-Pre). Finally the expression Tcontrol is used to set the temperature of the third inlet. Two step functions are used so that the temperature is equal to Tlower when Tout-Tm is positive (i.e. the outlet temperature is greater than Tm), and is equal to Tupper when Tout-Tm is positive.

CEL Technical Details CEL is a byte code compiled language. Compiled languages, such as FORTRAN, rely on a translation program to convert them into the native machine language of the host platform. Interpreted languages are of two types: the fully interpreted languages such as the UNIX C shell, and the byte code compiled languages such as CEL. With byte codes, host machines are loaded with a client program (written in a compiled language and compiled for that machine architecture) which interprets the byte stream. The advantage of the byte code is that they can be the same on all host platforms, obviating the need for platform dependent codes. Since the byte codes are interpreted, there is no need to re-link executable programs to perform a different calculation. Furthermore, many of the problems encountered by writing and linking in separate routines, for instance in C or FORTRAN, are averted, and the time taken to set up and debug complicated problems reduced considerably. The link between CEL and the CFX-5 Solver is accomplished through an internal program called genicode. Genicode generates intermediate code from your CEL definitions and writes to a file which is then interpreted by the CFX-5 Solver during the solution process.

Introduction to the Import Mesh API The Import Mesh Application Programming Interface allows you to build your own import mesh program using a set of utility subroutines. The API has been provided for those users who require mesh import capabilities beyond those available through the normal Import Mesh forms in CFX-Pre.

Valid Mesh Elements in CFX-5 The CFX-5 Solver can solve flows in any mesh comprising one or more of the following element types:

Tetrahedral

Prismatic (Wedge)

Pyramidal

Hexahedral

Your custom interface can be developed to support these element types allowing hybrid meshes to be imported and used by CFX-5.

CFX-5 Reference Guide Mesh Import API

Creating your own Mesh Import Program You can create your own customised Import Mesh program using the C programming language. Several mesh import utility routines are provided as libraries with the CFX-5 installation for you to incorporate into your own programs. You can also use one of the existing Import Mesh source routines as the basis of your custom mesh import program. The basic structure of the API is common in all of the examples: • Include cfxImport.h header file. • Initialise for import with the cfxImportInit routine. • Define node data with cfxImportNode. • Define element data with cfxImportElement. • Optionally define 2D and 3D regions with cfxImportRegion or cfxImportBegReg or cfxImportAddReg and cfxImportEndReg. • Finish the import and transfer data with cfxImportDone. The utility routine libraries are located in

/lib/// where is the directory in which CFX is installed, is the release number (e.g. 5.6) and is the operating system (e.g. solaris). More information on how to find out what these are for your system can be found in Document Conventions (p. 3 in Installing & Introduction to CFX-5). See API Functions (p. 46) for more details. The header files for the definition of the utility routines are located in

/include// The header file cfxImport.h should be included in your import program to define the API routines. After creating the program, you will need to link it with the API routine libraries and run it through CFX-Pre. See Linking your Code into CFX-5 (p. 43) and Using your Custom Import Format (p. 45) for more details. Note: Windows users should note that custom mesh import or export programs must be compiled as multi-threaded applications.

CFX-5 Reference Guide Mesh Import API

Linking your Code into CFX-5 In order to build an export utility routine, it must be linked with the Import API library. The library is named libmeshimport.a on UNIX and libmeshimport.lib on Windows platforms.

UNIX

On most UNIX systems you should be able to build the executable with the command: cc myimport.c -o myimport -L/lib// -lmeshimport -lio -lm -I/include//

where is the directory in which CFX is installed, is the release number (e.g. 5.6) and is the architecture of the machine that you are running on (e.g. one of solaris, irix, hpux, aix, osf,linux). To find out what is for your installation, see Specific Directory Names (p. 4 in Installing & Introduction to CFX-5). To find out what is for your machine, see Operating System Names (p. 5 in Installing & Introduction to CFX-5). In this example, your own import program is named myimport.c and the executable file will be called myimport. You should ensure that the libraries that you are linking to (the path given after -L) appear on the command line after the source file (or object file if you are just linking to an existing object).

Windows

On Windows systems, assuming that you are using the Microsoft Developer Studio which comes with Visual C++ version 5, you can do the following to build your executable: • Create a new project by selecting File > New, which should be a Win32 Console Application. • Specify the libraries which need to be linked in, by selecting Project > Add to Project > Files. Add Library Files libio.lib and libmeshimport.lib from the \lib\\winnt directory, where is the directory in which CFX is installed, is the release number (e.g. 5.6).

CFX-5.6

Linking your Code into CFX-5

Page 43

CFX-5 Reference Guide Mesh Import API

• Specify the header files which need to be included, by selecting Project > Settings. Select Settings for: All Configurations and the C/C++ tab, and select the Preprocessor category. You need to add the Additional Include Directory \include\\. • Next, you should create your C++ source file. Select New > C++ source file, and copy your C++ source file into the window for this file. • Before building the executable, you must choose to ignore the standard C and LIBCD libraries. To do this: under Project Settings, click on the Link tab and enter C,LIBCD in the Ignore Libraries box. • You must also compile with multithreading ON. Under Project Settings, click on the C/C++ tab, select Code Generation from the Category option menu, and select Multithreaded DLL from the Use run-time Library option menu. • To build the executable, select Build > Build <program_name>.exe, where <program_name> is the name of the project.

Using your Custom Import Format Running the program from CFX-Pre To access your routine, you need to select the mesh file to import on the Import Mesh Panel (p. 89 in CFX-Pre) form and set the Mesh Format to User Import. When this option is selected, you should select the Advanced tab, enter the name of your compiled program into the box marked Exec Location and enter any command line arguments that your program requires into the Exec Arguments box. When OK is pressed your program will be called with the syntax

<User’s Import Executable> <Executable Arguments> <Mesh file> Alternatively, to specify the executable program every time you start CFX-Pre, you can add the following line to your .cfx5rc file: CFX_IMPORT_EXEC="<executable_path>"

where <executable_path> is the full path and name of your executable. See Resources Set in cfx5rc Files (p. 162 in Installing & Introduction to CFX-5) for more details on .cfx5rc files. When you next use the User Import option for importing a mesh, the form will appear with the name of your executable in the User’s Import Executable databox.

API Functions This section lists the various routines available through the Mesh Import API that are available when you write your own customised program. A description of how to use the Import Mesh API is given in Creating your own Mesh Import Program (p. 37), and this includes information on how to write a customised Import Mesh program, how to link it into CFX-5, and how to run it. The locations of all the necessary files and libraries and an example are described in this document, and you are recommended to read it before trying to use any of the routines listed here.

Defined Constants The following are defined in the header file cfxImport.h, which should be included in the import program. Element Types There are currently 4 types of elements, which are identified by the number of nodes: Tetrahedrons (4 nodes), pyramids (5 nodes), wedges or prisms (6 nodes), and hexahedrons (8 nodes). The element types may be identified by the defined constants: #define #define #define #define

cfxELEM_TET cfxELEM_PYR cfxELEM_WDG cfxELEM_HEX

4 5 6 8

The element node ordering and local face numbering follow Patran Neutral file conventions for element descriptions. Region Types Regions may be defined in terms of nodes, faces or elements, based on the type argument to the cfxImportBegReg or cfxImportRegion routines. The three types are defined by the defined constants: #define cfxImpREG_NODES #define cfxImpREG_FACES #define cfxImpREG_ELEMS

Node and Face regions define 2D regions of the imported mesh. Element regions define 3D regions of the imported mesh. Page 46

API Functions

CFX-5.6

CFX-5 Reference Guide Mesh Import API

It is best to use face regions to define 2D regions of the mesh and element regions to define 3D regions of the mesh. Node regions will be automatically transformed into a face region by the import process. This transformation requires the node ID’s specified to define vertices of valid element faces. If no element faces can be constructed from the defined node region the node region will be deleted. Note: Due to the limited topological information recoverable from a set of nodes it is not advisable to define 2D regions internal to a 3D region using nodes. In this case it is advisable to use Face regions.

Node regions are specified by a list of node ID’s. Face regions are defined by a list of face ID’s. These face ID’s are a combination of an element ID and a local face number in the element. The following macro is provided in cfxImport.h to construct the face ID: #define cfxFACEID(elemid,facenum) ((elemid<<3)|(facenum&7))

In Fortran, the same operation may be done as: faceid = 8 * elemid + facenum

Element regions are specified as a list of element ID’s.

Initialisation Routines The following routines check and initialise the Import API. With the exception of cfxImportStatus the first call to the Import API must be either cfxImportInit for communication with CFX-5, or cfxImportTest for testing the import routine in stand-alone mode. cfxImportStatus int cfxImportStatus ()

Checks the current status of the connection to CFX-5 based on the state of the file descriptor associated with a communication channel. Returns 0 if descriptor is not opened and -1 if not opened for writing. In the normal case, 1 is returned if opened for writing to a CFX-5, and 2 if opened for writing to a file. cfxImportInit void cfxImportInit () CFX-5.6

API Functions

Page 47

CFX-5 Reference Guide Mesh Import API

Performs initialisation to begin communicating with CFX-5. This routine should be called early on in the import program to let CFX-5 know that data is to be sent. If not called within 60 seconds, CFX-5 will terminate the import process. If called and there is no connection with CFX-5, then the routine cfxImportTest("/dev/null") (UNIX) or cfxImportTest("null") (Windows) will be called. This routine will be automatically called by most of the API routines if not already called. There is no return value for this routine. In the case of an error, cfxImportFatal will be called. cfxImportTest int cfxImportTest (filename) char *filename;

This routine allows testing of import program in isolation from CFX-5 by writing data to a file filename instead of attempting to write it to the CFX-5 communication channel. The routine will return the file descriptor of the output file or will terminate with a call to cfxImportFatal on error.

Termination Routines With the exception of cfxImportTotals the last call to the Import API must always be cfxImportDone. This function performs the final processing of the import data, and then transfers the data to CFX-5. cfxImportDone long cfxImportDone ()

Indicate to the import API that all mesh data has been given and the API should now send the data to CFX-5. Except for cfxImportTotals, this should be last call made to the API. Returns the total number of bytes transferred to CFX-5 by the import program. cfxImportTotals long cfxImportTotals (counts) int counts[cfxImpCNT_SIZE];

Page 48

API Functions

CFX-5.6

CFX-5 Reference Guide Mesh Import API

Get the total number of nodes, elements, regions and other useful information given to the mesh import API by the program. This information is returned in the array counts, which should be of size at least cfxImpCNT_SIZE (currently defined as 9). The values returned in counts may be indexed by the enum list in cfxImport.h, which is: counts[cfxImpCNT_NODE] counts[cfxImpCNT_ELEMENT] counts[cfxImpCNT_REGION] counts[cfxImpCNT_UNUSED] counts[cfxImpCNT_DUP] counts[cfxImpCNT_TET] counts[cfxImpCNT_PYR] counts[cfxImpCNT_WDG] counts[cfxImpCNT_HEX]

= = = = = = = = =

number number number number number number number number number

of of of of of of of of of

nodes elements regions unused nodes duplicate nodes tetrahedral elements pyramid elements wedge elements hexahedral elements

The return value for the function is the total number of bytes of data sent to CFX-5 or written to the test file given when cfxImportTest was called.

Error Handling Routines The following two routines allow the programmer to define an error callback function, and a termination routine which terminates the import process cleanly. cfxImportError void cfxImportError (callback) void (*callback)(char *errmsg);

Define a user routine to be called before terminating due to a fatal error. callback is the application-supplied function to be called in the case of an error. The callback routine takes a single argument, errmsg, which will be passed by cfxImportFatal and should be processed by the callback function as a brief message describing the error that has occurred,. If this function is not called or callback is not specified, then the normal termination behaviour of the import mesh API will be that the any fatal errors will write the error message to stderr as well as being sent to CFX-5. cfxImportFatal void cfxImportFatal (errmsg) CFX-5.6

API Functions

Page 49

CFX-5 Reference Guide Mesh Import API

char *errmsg;

Terminate with an error message, errmsg. This routine will send the message to CFX-5, shut down the communication channel or test file and call the user callback function (if specified by a call to cfxImportError).

There is no return from this call. The import program will terminate immediately after clean up tasks have been performed.

Node Routines These routines define the 3D coordinates of points in space(nodes) which will be used to define elements or 2D regions which are to be imported to CFX-5. Each node has a unique identifier called a node ID. cfxImportNode int cfxImportNode (nodeid, x, y, z) int nodeid; double x, y, z;

Define a node in the import API to be subsequently imported into CFX-5. The unique identifier of the node is given by nodeid, and the coordinates of the node by x, y, and z. Returns 0 if nodeid is invalid (less than 1), -1 if the node had already been defined (in which case the node is redefined using the new coordinates), or nodeid if successfully defined. cfxImportGetNode int cfxImportGetNode (nodeid, x, y, z) int nodeid; double *x, *y, *z;

Get the coordinates for the node identified by nodeid and return the values in x, y, and z. Returns 0 if the node has not been defined or the node ID for the node. cfxImportNodeList int * cfxImportNodeList ()

Returns an array of all node identifiers currently defined or NULL if no nodes have been defined. The first entry in the array is the number of nodes currently defined. Page 50

API Functions

CFX-5.6

CFX-5 Reference Guide Mesh Import API

The memory for the array returned is allocated using malloc by the routine, consequently it should be destroyed when no longer required by calling free.

Element Routines The following routines define the topology of elements (using node ID’s) which are to be imported to CFX-5. Also included here are routines which get the local face number and vertices of an element. cfxImportElement int cfxImportElement (elemid, elemtype, nodelist) int elemid, elemtype, *nodelist;

Define a new element to be imported to CFX-5. The unique identifier of the element is given by elemid, the element type by elemtype and the list of vertices by nodelist. If an element with the same ID has already been defined, it will be replaced by the new element being defined. Only volume elements are currently supported by CFX-5; these may be tetrahedrons (4 vertices), pyramids (5 vertices), prisms (6 vertices) or hexahedrons (8 vertices). elemtype is the number of vertices for the element. The following defines are included in the header file, cfxImport.h for convenience: #define #define #define #define

cfxELEM_TET cfxELEM_PYR cfxELEM_WDG cfxELEM_HEX

4 5 6 8

/* /* /* /*

tet element (4 nodes ) */ pyramid element (5 nodes ) */ wedge element (6 nodes) */ hex element (8 nodes) */

The list of vertices in nodelist refers to ID’s of nodes which on termination of the import program by a call to cfxImportDone must have been defined by calls to cfxImportNode. If this is not the case a fatal error will be reported and the API will terminate. The vertex ordering for the elements follows Patran Neutral File element conventions, and is shown in the following figure.

Returns 0 in the case of an elemid is invalid (less than 1) or an unsupported value is given by elemtype, -1 if the element already exists and has been redefined , or elemtype if the element is successfully defined. cfxImportGetElement int cfxImportGetElement (elemid, nodelist) int elemid, nodelist[];

Get the node ID’s for corresponding to the vertices of element identified by elemid and store in the array nodelist. This array needs to be at least as large the number of vertices for the element (a size of 8 will handle all possible element types). Returns 0 if the element is not defined, or the element type (number of vertices). The node ID’s will be ordered in the order expected by cfxImportElement if the program was to redefine the element.

cfxImportElementList int * cfxImportElementList ()

Returns an array of all the currently defined element ID’s or NULL if no elements have been defined. The first entry in the array is the number of elements. The memory for the array returned is allocated using malloc by the routine, consequently it should be destroyed when no longer required by calling free. cfxImportGetFace int cfxImportGetFace (elemid, facenum, nodelist) int elemid, facenum, nodelist[];

Gets the node ID’s for the local facenum’th face of the element identified by elemid. The node ID’s is returned in nodelist, which should be of at least of size 4. The nodes correspond to the vertices of the face and are ordered counter-clockwise such that the normal for the face points away from the element. The face numbers, and associated node indices follows Patran Neutral File element and are detailed in the following table: Element Type

Returns -1 if the element has not been defined, 0 if the face number is out of range, or the number of nodes for the face (3 or 4): cfxImportFindFace int cfxImportFindFace (elemid, nnodes, nodeid) int elemid, nnodes, nodeid[];

Gets the local face number in element identified by elemid that contains all the nodes supplied by the calling routine in nodeid. nnodes is the number of nodes for the face (3 or 4). Returns -1 if the element is not found or nodeid is not supplied or nnodes is greater than 4 or less than 3. Returns 0 if there is no match, or the local face number (1 to 6) of the element.

Primitive Region Routines The following routines allow for the specification of 2D regions as a group of nodes or faces, or a 3D region as a group of elements. In the case of nodes and faces, only those which are define faces of valid imported elements will be imported; others are ignored by CFX-5. cfxImportBegReg int cfxImportBegReg (regname, regtype) char *regname; int regtype;

Initialise for the specification of a region. If a region is currently being defined, cfxImportEndReg will be called. Page 54

API Functions

CFX-5.6

CFX-5 Reference Guide Mesh Import API

The name of the region is given by regname. If the region name is NULL, the name Unnamed Region 2D or Unnamed Region 3D, with a sequential integer appended, will be used. If a region named regname has already been defined, then additional objects will be added to the previous region. The type of region is given by regtype, which should be one of cfxImpREG_NODES, cfxImpREG_FACES or cfxImpREG_ELEMS depending on whether the region is to be defined by nodes, faces or elements, respectively. It is not currently possible to mix types in a region; doing so will cause the import API to terminate with an error message. Returns the number of objects (node, faces or elements) currently in the region. cfxImportAddReg int cfxImportAddReg (numobjs, objlist) int numobjs, *objlist;

Add ID’s of objects being defined to the current region. A region must be currently defined or reactivated by cfxImportBegReg or an error will occur, and the API will terminate. The number of objects to add is given by numobjs and the ID’s of the objects are supplied in objlist. The objects are interpreted as node ID’s, face ID’s, or element ID’s, depending on the type of the region indicated when cfxImportBegReg was called. On calling cfxImportDone, any node ID’s , face ID’s or element ID’s specified in the object list must have been defined by the appropriate routine or they will be removed from the region. Returns the total number of objects in the current region after the object ID’s have been added. cfxImportEndReg int cfxImportEndReg ()

End the specification of the current region. Returns the number of objects (nodes, faces or elements) in the region.

CFX-5 Reference Guide Mesh Import API

cfxImportRegion int cfxImportRegion (regname, regtype, numobjs, objlist) char *regname; int regtype, numobjs, *objlist;

Import a region named regname of type regtype. The number of objects to add to the region is given by numobjs, and the list of object ID’s by objlist. This routine combines calls to cfxImportBegReg, cfxImportAddReg and cfxImportEndReg. Returns the total number of objects in the region on termination of the routine. cfxImportRegionList char ** cfxImportRegionList ()

Return a NULL terminated list of currently defined region names. The memory for the array and each character string in the array returned is allocated using malloc by the routine, consequently each array member and the array itself should be destroyed when no longer required by calling free. cfxImportGetRegion int * cfxImportGetRegion (regname) char *regname;

Returns a list of objects in the region named regname, or NULL if the region does not exist. The first entry in the returned list is the region type and the second entry is the number of object ID’s. The memory for the array is allocated using malloc by the routine, consequently the array itself should be destroyed when no longer required by calling free.

Composite Regions Routines The following routines allow composite regions to be defined in terms of regions referring to object ID’s or other composite regions. cfxImportBegCompRegion cfxImportBegCompReg() char *regionName; Page 56

API Functions

CFX-5.6

CFX-5 Reference Guide Mesh Import API

Begin defining a composite region with the name regionName, Returns -1 if a primitive region regionName is already defined or memory couldn’t be allocated, or 0 if successfully created. cfxImportAddCompRegComponents int cfxImportAddCompRegComponents(componentCount,components) int componentCount; char **components;

Add a set of component region names specified in components to the composite region currently being defined. componentCount specified how many components are specified in the components array, Returns -1 if a composite region isn’t being defined or insufficient memory is available to add the components of the composite region, or 0 if the components were successfully added. cfxImportEndCompReg int cfxImportEndCompReg()

Finish defining the current composite region. Returns -1 if a composite region isn’t currently being defined or 0 otherwise. cfxImportCompositeRegion int cfxImportCompositeRegion(regionName, componentCount, components) char *regionName, **components; int componentCount;

Define a composite region named regionName with componentCount components supplied in character array components. Returns 0 if successful or -1 if an error occurred preventing the composite region being defined.

Explicit Node Pairing The following routine provides a method for explicitly marking two nodes as being identical (or in the same position in space).

CFX-5.6

API Functions

Page 57

CFX-5 Reference Guide Mesh Import API

cfxImportMap int cfxImportMap (nodeid, mapid) int nodeid, mapid;

Explicitly map the node identified by nodeid to the node identified by mapid. On calling cfxImportDone the Import Mesh API will update regions and elements referencing the mapped node to the node it is mapped to. This therefore reduces the total node count imported to CFX-5 and eliminates the duplicate nodes. Duplicate nodes may also be removed by CFX-5 if the appropriate options are turned on in the CFX-5 interface and an appropriate tolerance set. See Import Mesh Panel (p. 89 in CFX-Pre).

Import Programs The following documents the currently available import programs and their command line options. Each of these are available from within the CFX-Pre User Interface and you are strongly advised to use them by selecting the appropriate mesh type on the Import Mesh form, rather than running them directly using the User Import option, wherever possible. See Import Mesh Panel (p. 89 in CFX-Pre) for more details on the Import Mesh form. If you wish to use command line options which cannot be specified through the CFX-Pre User Interface, then you may wish to run these programs as user-defined mesh import programs. See Using your Custom Import Format (p. 45) for details on how to run a mesh import program. The programs can be found in /bin// /, where is the directory in which CFX is installed, is the release number (e.g. 5.6) and is the architecture of the machine that you are running on (e.g. one of solaris, irix, hpux, aix, osf, winnt, linux). To find out what is for your installation, see Specific Directory Names (p. 4 in Installing & Introduction to CFX-5). To find out what is for your machine, see Operating System Names (p. 5 in Installing & Introduction to CFX-5).

TASCflow v2 Imports TASCflow Version 2 files. The external import routine is ImportGRD. The import routine will read the interface information from the GRD file and automatically remove duplicate nodes, thus the duplicate node checking (options -d and -D) is unneeded. Available command line options are: -v Verbose output. Echo additional data to stdout during the import. -V More verbose output. -i Ignore the blockoff file (BCF). -c Ignore GCI file. -o Old style 2.4 format. -b Specifies bcf file which contains blocked-off regions (boundary condition information is ignored. See CFX-TASCflow v2 (p. 93 in CFX-Pre)).

CFX-5.6

CFX-5 Reference Guide Mesh Import API

The external import routine is ImportPDC. The import routine will attempt to determine the connectivity file associated with the grid file by appending the extension conn to the grid file name. If the file is not found, then the grid file name extension will be replaced by conn and the new file checked for. If neither of these are found, the import routine will look for a file named conn.tmp, and if found will use it. A command line option (-c) is also available to explicitly name the connectivity file. If a connectivity file is found, the interface information in the file will be used to eliminate the duplicate nodes at block interfaces, and boundaries conditions will be imported as regions into CFX-5. If the boundary condition is named in the connectivity file, then that name will be used for the region name, else the default name UnnamedRegionX with the X replaced by a number will be used. If a connectivity file is not found, or the command line option to ignore the connectivity file is given (-i), then only the grid file will be imported, resulting in duplicate nodes at the block interfaces. You may then wish to eliminate these duplicate nodes with the command line option (-d or -D). Available options are: -v Verbose output. Echo additional data to stdout during the import. -i Ignore the connectivity file. Duplicate nodes will result and no regions will be imported. -c Set the name of the connectivity file associated with the grid file to connfile. -p Include periodic boundary conditions as regions. These are not normally included in the import. Setting this flag will result in these being imported as regions. -q Read from the property file -P <propfile> Set the name of the property file associated with the grid file to propfile. -3 Import grid blocks as 3-D regions

Echo additional data to stdout during the import. -b Read a grid from the specific CGNS base. -B Read all CGNS bases. (default) -c Read BOCO information as 2D regions. SplitCGNS.exe The SplitCGNS.exe program will take a single CGNS file and split it into multiple files on a "file per problem basis". The method for running this is: SplitCGNS.exe [ -l ] If the file contains two problems called "Pipe" and "Elbow", the import filter will only currently read "Pipe", but using SplitCGNS will produce two files called basename_Pipe.cgns and basename_Elbow.cgns each containing a single problem which can then be selected for import via the normal method.

Specifying the "-l" option "links" the part of the data in the original file to the created file using a relative pathname. The created file does not therefore need to duplicate data. The "-l" option should only be used if the original file and resulting files are going to be kept relative to each other i.e. if when SplitCGNS was run the original file was in ../../example.cgns, it must always remain in this position relative to the created files.

The Answers General • What does it mean when menu items in the Top Window have a character which is underlined or three dots at the end? The underlined character is there to provide a keyboard short-cut so that you can select an item from the menu without using the mouse. See Using Keyboard Mnemonics to Open a Menu (p. 34 in CFX-Build). The three dots at the end of the names listed in the menus signify that clicking upon that name will open up a form. If you select a menu item without three dots at the end, then that will usually result in a single action which is performed immediately. • What is meant by and how can I find it out for my installation?

is the directory in which CFX is installed. If you are asked to type something which includes the symbol , you should substitute this directory name for the symbol. To find out what this directory is for your installation, see Specific Directory Names (p. 4 in Installing & Introduction to CFX-5). • Where should my CFX-5 setup files be placed if I’m using a Windows machine? If you have a “home” directory on a Windows machine, then you can place your setup files in this directory. On Windows NT, some files can also be placed in c:\winnt\profiles\<user>\Application Data\CFX-5\ (where <user> is your user name) or in the current directory. On Windows 2000, files can be placed in Settings\<user>\Application Data\CFX-5\. CFX-5 setup files are described in Customising CFX-5 (p. 159 in Installing & Introduction to CFX-5). • How can I print my files on a Windows system if I don’t have a PostScript printer? There are various viewers of PostScript files for Windows systems which will allow you to print PostScript files without a PostScriptcapable printer. You can find one available for downloading at http:// www.cs.wisc.edu/~ghost/ and others are available. Note that we cannot provide any support for the use of these products.

Help Documentation • Do I have to purchase FrameViewer to look at the online help? No, CFX-5 online help can be viewed in PDF format with Adobe Acrobat Reader, which is supplied with your installation. The only aspect of the documentation that needs FrameViewer is CFX-Build context-sensitive help. • How can I browse the online help without opening CFX-Build, CFX-Pre, the CFX-5 Solver Manager or CFX-Post? You can open the online help from the Help menu on the CFX-5 Launcher. See Accessing PDF Online Help (p. 224 in Installing & Introduction to CFX-5) for more details. You can also type the command cfx5help in a UNIX terminal or a suitable Windows command line and press the Return key. (Windows command lines are discussed in Command line (p. 216 in Installation & Introduction to CFX-5).) The Master Contents page of the online help will be opened, and you can navigate to any place you require by following the links on this page. • How can I obtain a good quality printed document? In the CFX-5 Help menu, click on Printable Books. For CFX-Build, you can find Printable Books in the Tools menu. In the books.pdf file that opens, select the book you wish to print and click on File > Print in Adobe Acrobat Reader. Please check the number of pages in the book you choose before you print it as some of the books contain over 1000 pages. See Printing PDF Documents (p. 229 in Installing & Introduction to CFX-5) for more details. • How do I search the PDF online documentation? You must have Adobe Acrobat Reader with Search. Click the Search icon on the Reader main menu. In the Adobe Acrobat Search panel, type a keyword and click the Search button. A list of files showing your results will appear.

A search index is a file created using Adobe Acrobat that contains an organised list of all the keywords in the documentation. Search index files have the suffix .pdx. These files allow you to search the thousands of pages of CFX-5 documentation in seconds. Each version of CFX-5 has its own search index and you can search any number of indexes at one time. To load a search index, click the Search icon on the Acrobat Reader main menu. In the Adobe Acrobat Search panel, click the Indexes button. In the Index Selection panel, check the box next to the index you want to search and click OK. If you cannot find the index you want, click the Add... button and browse for the search.pdx file. You will find it in the same directory as your CFX-5 PDF files. To remove a search index, highlight it in the Index Selection panel and click the Remove button. • I can’t find the

Search icon in Acrobat Reader. If you have Adobe Acrobat Reader open, and there is no Search icon on the main menu bar, you have a version of Reader that does not support the search capability. In order to provide full help functionality, you should download the version of Adobe Acrobat Reader WITH SEARCH that is available on the CFX-5 CD.

• Nothing happens when I click the Search button in the Acrobat Reader Search panel. You have no search index loaded. The following message will be at the bottom of the Adobe Acrobat Search panel: “No selected indexes are available for search.” For information on how to load search indexes, see the question above What are search indexes and how do I add and remove them from the PDF searches? • When I press F1 nothing happens. If you are in a component other than CFX-Build, you are probably trying to use PDF context help with no Acrobat Reader installed. If no Acrobat Reader is installed on your system, you will get an error similar to: Error returned from help viewer: initialiseReader: unable to find a valid path to the reader. Please set CFX_PDF_READCMD to the path of a valid reader executable. For UNIX systems, it is highly recommended that you install Adobe Acrobat Reader with Search when you install the CFX-5.6 software. You must use the Adobe Acrobat Reader supplied with CFX-5.6 to provide full help functionality.This contains additional plug-ins to allow context sensitive help to function. These plug-ins will not be included with any other installation of Adobe Acrobat Reader. Page 626

In order to use F1 help (also called context-sensitive help) in CFX-Build, you need to have FrameViewer. If you do not have FrameViewer and you pressed F1 in CFX-Build, a message appeared in the command line window: Waiting for FrameViewer to become available. then another message: No response from FrameViewer RPC server after 60 seconds. FrameViewer was available with the CFX-5.5.1 CD, but is no longer supplied with CFX-5. If you do not have FrameViewer, Help in PDF format is still available in CFX-Build through the Tools menu, but F1 help with CFX-Build will not work. • I’m running Windows 2000/XP and some of my fonts display incorrectly in FrameViewer. A workaround for this problem is documented in Odd Characters in FrameViewer Files with Windows 2000/XP (p. 232 in Installing & Introduction to CFX-5). • CFX-Build online help fails with the message “No response from FrameViewer RPC server...” If you receive the error message “No response from FrameViewer RPC server after 60 seconds” when you try to open CFX-Build FrameViewer online help, check the host settings by typing the commands uname n and hostname. The output from both of these commands must be identical. Inform your systems administrator of the problem if this is not the case. These settings are most often incorrect on IRIX systems when running CFX-5.4 or earlier.

CFX-Build Session files, journal files and databases • What is the difference between a Journal File (.jou) and a Session File (.ses)? The Journal File contains all the commands required to recreate your CFX-Build model database, i.e. it is specific to a particular model. It can therefore contain commands from many CFX-Build sessions. CFX-5.6

The Answers

CFX-5 Reference Guide Frequently Asked Questions

The Session File is a record of all the commands (and CFX-Build responses) from a particular CFX-Build session. It can therefore contain commands which relate to operations on more than one database. For example, if you open a database, close it, and then open another database, all of these actions will be recorded in the Session File. • I’m having trouble playing back a Session File. It may be that you are trying to play back a Session File which was created on a different computer platform. If you transported your session file from one platform to another, then you must first edit your Session File to change the machine name part of the template name argument for the command which starts the playback. Alternatively, you can use the File>Rebuild command from the CFX-Build Main Menu to rebuild your model from a Journal File. Journal Files are machine independent. • Can I use old CFX-Build 5 databases with the current version of CFX-Build? You can open a CFX-Build 5.4 UNIX (or later) or CFX-Build 5.3 Windows (or later) database on any operating system in CFX-Build by selecting File > Open. No explicit conversion is required. You should note that after opening the database in CFX-5.6, you will not be able to open it again in earlier versions. If you need to be able to do this, you should make a copy of the old database before opening it. • How can I use a database created on one machine type on a machine of a different type? CFX-5.6 databases can be opened on any operating system without conversion. However, you should note that if you open databases created on a Windows or Compaq Tru 64 Unix machine on any other UNIX platform (or vice versa), the process of opening the database will take longer than usual. Geometry modelling • I can’t mesh imported Parasolid solids when using multiple solids. When you import Parasolid solids into CFX-Build that apparently share boundaries, you must be very careful in checking the shared faces between solids and surfaces which reference the underlying CAD geometry.

The Answers

CFX-5.6

CFX-5 Reference Guide Frequently Asked Questions

The key to this problem is to disassemble the solids and carefully examine the surfaces produced. It is often the case that two apparently common surfaces between two solids are referencing different surfaces. This causes a topological error and trips up the meshing algorithms. To solve the problem, first disassemble the solids that appear to be sharing a face. Next, recreate the solids ensuring that both solids use the exact same surface at the bounding interface. One of the surfaces at the boundary can be deleted to aid this process. • Why can’t I pick a particular Curve/Edge/Surface/Face? Before picking a geometric entity, you should choose which type of entity you want to pick, using the Select Menu form. The most common problem new users have is trying to pick an edge of a surface which is not an explicit curve. ? Pick Any point Pick an existing Point Pick an existing Node

For details, see Using the Select Menus (p. 45 in CFX-Build). • I can only select some geometry entities when I use the mouse. You can change the way you select entities by using the Picking Preferences form, available by selecting Preferences > Picking from the CFX-Build Main Menu. This setting determines whether an entity is ‘picked’ depending on the location of the cursor.

An additional picking utility is provided on the Select Menu form, which accompanies many of the forms in CFX-Build. The “Pick Visible Entities” icon disables Preselection Highlighting and allows you to pick only those entities which you would normally be able to view. Pick Visible Entities

?

For instance, enabling this icon would allow you to pick only the three visible surfaces of a solid cube. For details, see Using the Select Menus (p. 45 in CFX-Build). • A message appeared about “visible entity picking” and then when I wanted to select something from the viewport, nothing was highlighted as I moved the mouse over it. You have accidentally changed the picking mode from “Pre-selection highlighting” to “Visible entity picking”. By default, if you click in a databox which requires you to select a geometrical object or a mesh entity (e.g. a surface), then when you move the mouse over the viewport, each object of the appropriate type is highlighted as the mouse passes over it. In this way, you can see which object you would pick if you were to click the mouse button in that position - this is called “pre-selection highlighting”. You can pick any object of an appropriate type, even if there is another entity in front of it. However, CFX-Build has a different mode of operation in which there is no pre-selection highlighting and where you can only pick entities that are at the front of the viewport - entities which are entirely behind another entity of the same sort cannot be selected.

To toggle between these two modes, use the toggle on the Select menu, as shown below. Toggle to switch ON/ OFF visible entity picking mode.

Also see I can only select some geometry entities when I use the mouse. (p. 629). • I tried to create a B-rep and I get a gap warning message. CFX-Build gives the following warning: A Gap exists between two of the faces in the Body. This may be due to edges not matching directly or a missing face. Edges are hilighted. Use Edit/Surface/Edge Match to close the gaps, then use Create/Solid/B-rep to create the solid.

and the B-rep solid is not created. When you press OK, the problem edges are highlighted with red coloured markers at the vertices. The reason for this is that CFX-Build has found gaps in your model between original surfaces, or those which were created by breaking other surfaces. This problem is called incongruency, and can occur when surfaces do not meet exactly at their edges, which is a requirement for defining a fully enclosed volume. Fortunately, CFX-Build provides a function which allows you to correct this problem automatically. The sew function (Edit/Surface/Sew) is a composite geometry action which first equivalences (or merges) surface edge points, and then merges the associated edges using an edge matching procedure. Use this first, and then create your B-rep solid. Refer to Text Files in the section Transferring and Upgrading CFX-Build Files (p. 127 in CFX-Build). Also see Play Session File (p. 222 in CFX-Build). • I’ve lost objects, but I know I haven’t deleted them. If you delete a group, it is possible for objects to become ‘orphans’, i.e. they don’t belong to any group. You can only display objects which are in a group, so orphan objects cannot be displayed. To overcome this problem, create a new group and select Add All Orphans as the selection type. CFX-5.6
