Hi everyone I wrote an UDF for wall heat generation rate in this model
Cattura.PNG
For the heat generation rate the UDF is:

#include "udf.h"
DEFINE_PROFILE(wallheatgenerate,thread,i)
{
face_t f;
real t = CURRENT_TIME ;
real source = 4.1e+06*t;
begin_f_loop(f,thread)
{
F_PROFILE(f,thread,i) = source;
}
end_f_loop(f,thread)

}

The UDF is interpreted correctly,and then is been hooked in the wall generation rate of the small sphere inside the inner cylinder.
The problem is When I calculate the solution: I got a total heat transfer rate for the wall-shpere of -1.43e-06 like no heat is been generated,instead I put a sorce with a big value (4.1e+06 !!!!).
Anyone knows where the problem is???
Thank you very much
