I have written a udf for introducing moisture over coupled wall between two fluids.

#include "udf.h"

#define m 0.28

DEFINE_PROFILE(mass_H2O,t,i)

{

face_t f;

real x[ND_ND];

real A[ND_ND];

real y;

begin_f_loop(f,t)

{

F_AREA(A,f,t);

F_CENTROID(x,f,t);

F_YI(x,f,t);

y=m*F_YI(x,f,t);

}

End_f_loop(f,t)

}

Please help me. This UDF is showing nothing in the contours.
? In my case, I have two inlets and two outlets of two different fluids and in between there is a sandwiched (Coupled wall). In inlets of both fluids I am introducing velocity of fluids along with temperature while both outlets are set for pressure outlets. And in this coupled wall option I have option in species where there are boundary condition. I am confused where I will introduce UDF.
