Hi all,

I had input the below file to the FLUENT as boundary condition. why its not work ? where is my mistake? I know its not work becuase after analysis the fluent used constant temperature (its default value).


start the program:


#include "udf.h"

DEFINE_PROFILE(Temp_Profile, thread, position)
{
face_t f;
real x[ND_ND]; /* this will hold the position vector */
real y;

begin_f_loop(f, thread)
{
F_CENTROID(x,f,thread);
y = x[0];
F_PROFILE(f, thread, position) = (9e-5*y*y*y*y*y)-(0.0038*y*y*y*y)+(0.028*y*y*y)+(0.3856*y*y)-(2.3528*y)+11.456;

}
end_f_loop(f,t)
}
