Urgent: Random number in UDF
 

Hi,

Can anyone tell me which function to use to generate uniform random numbers in (0~1) or Gaussian random numbers in Fluent UDF?

URGENT, S.O.S.!

Hi, Your UDF is programmed in C, so that I think you can only use C language to generate random numbers.

The function rand() is defined in sdtlib.h.

Have a look to the following links:
