fluent udf---I need help
Dear friends,
I am a new of using fluent.Recently I want to compare my results with fluent.At the free surface the y-direction gradient of x-direction velocity u and x-direction gradient of temperature have a relation as follows:
du/dy=-dT/dx,dT/dy=0. I write my udf as follows ,but fluent will feed back error when I initialize .Could give me some help ? because most of the time I can not access to this web,so are you kind to contact me at Best wishes !

/************************************************** ****************************

#include "udf.h"
real xigema = -1; /* the coefficient after dimensioned */

cell_t c;
begin_c_loop(c, thread)
end_c_loop(c, thread)
