KR449: Do I really need to learn how to write UDFs for basic use of FLUENT software? |
Basic use does not require knowledge of UDFs. However, special customizations may need UDFs. |
KR450: What are the UDF resources available to me? |
UDF manual:<br><a target=_blank... |
KR451: How can I monitor forces during my simulation using Newtons instead of dimensionless coefficients in FLUENT? |
FLUENT always monitors forces using dimensionless coefficients. These are defined as<br><br>Coefficient = Force/(0.5ρV2A) ... |
KR452: How can I read a journal (a) from a journal or (b) using execute commands in FLUENT? |
FLUENT will not allow the user to have the command<br><br>/file/read-journal myjournal.jou (1)<br><br>within a journal file or as an execute command. However, FLUENT... |
KR453: How can I calculate Time-Integrated Quantities in CFD-Post? |
See attached PDF |
KR454: What is the best way to sample the mass flow rate in a transient run in FLUENT? |
To get transient mass flow rate data, you need to use the surface monitor functionality under Solution->Monitors..<br><br>Let's say, you want to write out mass flow rate... |
KR455: What are some scenarios where I would need a UDF? |
Please refer to following link in the user manual for details.<br><br><a target=_blank... |
KR456: How can I learn the basics of UDF writing? |
UDF code is written in C language. A working knowledge of C makes it easy to pick up UDFs. |
KR457: What compiler do I need for a PC? |
You need a Microsoft Visual C++ compiler for PCs. More details at:<br><a target=_blank... |
KR458: What's the difference: UDF/SCHEME/Macros? |
UDFs are functions that are written in a combination of C language and FLUENT macros.<br><br>FLUENT macros are pre-defined function templates that the FLUENT solver can... |
KR459: What is a good resource to learn scheme programming? |
Please refer to the following link.<br><br><a target=_blank href="http://www.scheme.com/tspl3/">http://www.scheme.com/tspl3/</a>http://www.scheme.com/tspl3/ |
KR460: How do I link my udf to FLUENT? Do I need to compile FLUENT source code with my UDF? |
You do not need to compile the Fluent source code. Once a UDF is loaded, the functions need to be hooked to the relevant location in the graphical user interface. |
KR461: Can I write my UDF in Fortran or C++? |
UDFs must be written in the C programming language and they typically use Fluent supplied macros. |
KR462: What are the steps in using a UDF in my case file? |
COMPILED UDFs<br><br>1. Compile the UDF<br> a. Define > User-Defined > Functions > Compiled<br> b. Browse and add the relevant... |
KR463: Do you have a template for all UDFs (like FIDAP does)? |
Though there are no ready-made templates for UDFs, there are many examples of UDF macros in the UDF manual. These can be customized as needed. |
KR464: How can I add my own material properties? |
If you have material properties that cannot be defined using one of the many options provided in the Materials panel, you can use a DEFINE_PROPERTY UDF. Details and examples are shown in the... |
KR465: How do I specify a polynomial profile at the inlet? |
You will use a DEFINE_PROFILE macro in your UDF. Details and examples are shown in the manual at:<br><br><a target=_blank... |
KR466: What is the difference between interpreted and compiled UDFs? |
The major difference between interpreted and compiled UDFs is that interpreted UDFs cannot access FLUENT solver data using direct structure references; they can only indirectly access data through... |
KR467: EXECUTE_ON_DEMAND vs. DEFINE_ADJUST and DEFINE_EXECUTE_AT_END |
An EXECUTE_ON_DEMAND macro is executed only when explicitly called, a DEFINE_ADJUST macro is called at the beginning of every iteration and a DEFINE_EXECUTE_AT_END macro is called at end of every... |
