This file needs to be placed in home directory (location where FLUENT executables are placed during installation).

FLUENT GUI is based on Qt Toolkit and graphical attributes can be modified using Qt stylesheets such as cxdisplay.css for FLUENT. In such cases, end-to-end automation may not yield desired advantages and a separate automation should be worked out at each step. For example, ANSYS SpaceClaim uses Python, FLUENT is based on SCHEME and the syntax in CFD-Post is CEL/PERL. It may be an uphill task if the CAD program, the pre-processors and solvers uses different programming and scripting languages. Even the structure of CAD program (such as model tree) to represent an assembly need to be simple and consistent with CFD pre-processor. This include CAD package, the pre-processor, solve and post-processor. Note that specific heat capacity Cp cannot be accessed or changed via UDF in FLUENT.Ī sophisticated automation approach requires developement of a consistent naming convention for the geometry, surface, boundaries and volumetric regions (domains).However, for special post processing, commands in PERL and accessing solver program in FORTRAN is required.

Unlike UDF or JAVA macros, it does not need to be interpreted or compiled.

CFX uses a high level programming called CCL or CFX command language.

A FLUENT UDF is a C program that is compiled and executed within the FLUENT workspace.

A STAR-CCM+ macro is a Java program that is compiled and executed within the STAR-CCM+ workspace.

Scripts or macros can be used to repeat the same simulation with changed boundary conditions or can be used to create a checking log where the summary of boundary conditions, solver setting, material properties and interface/periodicity information can be written out in a log file for self and peer review.

One may need such functions to apply special boundary conditions such as inlet velocity which is function of both time and space. Automation Scripts, Journals, UDF, Field FunctionsĪ collection of scripts, journals and macros in CFD simulations to automate some tasks as well as enhance simulation capabilities.
