UDF of iterations
 

I want to have UDF :

from 1 ~ 500 iteration , pressure-outlet=101000pa

when 500 iteration finished, 101200pa.

file of *.c is below, but have error.

Anyone help me? ............................................. #include "udf.h"

DEFINE_PROFILE(unsteady_velocity, thread, position) { face_t f; int iter;

iter = N_ITER;

if (iter < 500)

F_PROFILE(f, thread, position) = 101000; else

F_PROFILE(f, thread, position) = 101200;

} .................................................. ..

Re: UDF of iterations
 

As far as I understood, you want to have a pressure outlet b.c. of a value 101000pa when ite. lower than 500 and 101200 pa after 500 ite. I think, you won't get a b.c. like that, even your UDF runs fine, because hooking for UDF can not be made in UDF itself. You must do it manually...

good luck...

Hi,

"nres" should be used instead of "N_ITER".

It is OK!

Thank you very very much!

hi,
I am using nres in my udf, but i can tell the difference between nres and N_ITER, can you explain it?

thanks
