UDF help------------
 

My following UDF compiled and run well but I get 0 in the UDMI. Can anybody what is the problem?

#define <mem.h>

DEFINE_ON_DEMAND(on_demand_WallShear) {

Thread *tf;

cell_t c;

face_t f;

int ID =3;

Domain *domain;

real NV_VEC(A);

domain = Get_Domain(1);

tf = Lookup_Thread(domain,ID);

begin_f_loop(f, tf)

{

F_AREA(A,f,tf);

F_UDMI(f,tf,1)= NV_MAG(A);

}

end_f_loop(f, tf)

}

you need to store the value using F_UDMI and C_UDMI. then display with node values turned off in Fluent
