hello, I don't know how to call random generator in Fluent by using UDF. I found this function in random.h that locate in fluent\src folder. If you know the answer, please reply. Thanks in advance.

You can use the random generator functions of the C compiler:

The function

randomize();

initializes the random number generator, while the function

random(int n);

generates a random number between 0 and n-1.

Look on google for further details. Here there is an example (if you remove random.html, you have access to a guide to C):

Hi

I forgot to say, you need to include stdlib.h

#include <stdlib.h>

and use compiled UDF.
