UDF von neumann
 

#include udf.h
DEFINE_PROFILE(von_neumann,thread,index)
{
face_t f;
Thread *t;
cell_t c0;
Thread *t0;
begin_f_loop(f,t)
{
F_PROFILE(f,t,i)=C_U(c0,t0);
}
end_f_loop(f,t)
}

This is the udf i framed for the gradient boundary condition du/dy=0. But i want this udf to be executed at the end. But if i use execute_at_end macro, will i be able to declare the index i for the F_PROFILE(f,t,i). Please help.


Thank you
