Hi all,

I am trying to write a UDF to simulate a pressure jump over a fan. The UDF is written for a 2D model with a line (face) to simulate the fan.

Can somebody detect the mistake i have made. Cause the setup doestn't want to initialize.

#include "udf.h"
DEFINE_PROFILE(pressure_rise, thread, position)
{
face_t f;
real p;
begin_f_loop(f, thread)
{
p = F_P(f,thread);
F_PROFILE(f, thread, position) = p + 4000;
}
end_f_loop(f, thread)
}

vasava will become famous soon enough
Instead of F_P(f,thread) try C_P(c,t).
