Hi everybody. I had the exact same problem and here's how I solved it:

Situation:
- I am currently using the Fluent package contained in Ansys v12.0
- I am working on a Windows 7 (32 bit) OS
- I have installed "Microsoft Visual C++ 2008 - Express Edition" (I've also tried with the Visual C++ 2010 but it seems not to be compatible with Ansys v12.0)

Solution:
- I've modified my environment variables in this way:

1) Start -> Computer -> Properties -> Advanced Options -> Environment variables -> PATH -> Edit

2) I've then added the following adresses to the existing list:
- C:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools;
- C:\Program Files\Microsoft Visual Studio 9.0\VC\bin;
- C:\Program Files\ANSYS Inc\v120\fluent\ntbin\ntx86;

- Then I've created a folder "TEST" where I put my case files AND the .c file containing my udf "udf_test.c"

- I've opened my case's workbench and double-clicked on "setup", opening FLUENT

- Define -> User-Defined -> Functions -> Compiled

- Now on Source Files I've added my source file "udf_test.c"

- On "library name" I've kept the default library name "libudf" and clicked on the "Build" button

- Now, on the working directory "TEST", FLUENT created a new folder containing the library and called "libudf"

- I've then copied the "libudf" directory and pasted it into: mycase_files -> dp0 -> FFF -> Fluent

- At last I clicked on the LOAD button in Fluent, and my udf library was successfully loaded in Fluent

Hope it will work for you as well.

Hi,

I had the same problem when I run Fluent in windows. But then I installed VisualC++, everything worked. It seems that you need to have a compiler installed in the computer. This is how I solved my problem.

Here are the steps, I do to run an Udf file.

1- put the udf file in my case directory.

2- Go to Define>user-defined Functions>Compiled> There you should first add the udf file.

3- Click on BUILD

4- Click on LOAD

..it should work.

can you show step by step what you do by attached flie
thanks you so much

In my case,
1. first install SDK 2.0
2. Open SDK 2.0 command prompt, type: Fluent
3. Then go to Define>User Defined> Function> Compiler

Remember to put the udf file in the same folder with case files
