Hi, I am a newbie on UDFs and I have a problem that maybe is easy or even for some of you who have a lot of experience.

From the fluent's UDF manual I copied an example and changed a function to get the following UDF

/************************************************** ********************
unsteady.c
UDF for specifying a transient velocity profile boundary condition
************************************************** *********************/
#include "udf.h"
DEFINE_PROFILE(unsteady_velocity, thread, position)
{
face_t f;
real t = CURRENT_TIME;
begin_f_loop(f, thread)
{
F_PROFILE(f, thread, position) = 0.5*t;
}
end_f_loop(f, thread)
}

It works when I run it in serial fluent, but it does not work when I try to run the simulation in parallel fluent. I have read the manual but I honestly dont know how to make it work.

It would be great if someone told me what should I add or change to make it work for parallel fluent.

Thanks for any reply,

Elias
