[Field Function]

Hi everybody, I'm from Vietnam. I'm an CFD engineer.Previous I used ANSYS Fluent to simulate but now, I'm using Star CCM+ software to simulate for HVAC project. because of I just used this software in few weeks. So I have a problem. I hope that everybody help me.

I want to hook C language code (similar ANSYS Fluent) into STAR CCM+ to wind speed calculate. I don't know how to do. This is my code. Please help me

#include "udf.h"

DEFINE_PROFILE(log_velocity,thread,index)

{

real y[ND_ND];

real z;

face_t f;

begin_f_loop(f,thread)

{

F_CENTROID(y,f,thread);

    z = y[1];

    F_PROFILE(f,thread,index) = 3.7*log(z/0.6)/log(10.0/0.6);

}

end_f_loop(f,thread)

}
