I have written the following code to display the pressure contour using user define memory.


#include "udf.h"

DEFINE_ON_DEMAND(wall_pressure)

{ face_t f;
Domain *domain=Get_Domain(1);
int ID = 8;

/* Zone ID for wall zone */

Thread *t = Lookup_Thread(domain, ID);

begin_f_loop(f, t)

{

F_UDMI(f,t,0) = F_P(f,t);

Message("pressure %e\n",F_UDMI(f,t,0));

}

end_f_loop(f, t)

}

But the contour displays only zeros, i even tried to replace F_P(f,t) with 300 but i still end up getting the same zero result.

Could you let me know the reason behind the result?
