Hi guys, I am new to udf flent. i wanted to give a temperature profile along the wall, so I wanted to create a udf for temperature change along the wall as a function of length of the nozzle. I have created one, can anyone please tell me if its correct

#include "udf.h"

DEFINE PROFILE(temp,t,i)
{
real x[ND_ND];
real x0;
face_t f;
begin_f_loop(f,t)
{
F_CENTROID(x,f,t);
x0=x[0];

F_PROFILE(f,thread,position)=T_n+(T_(n+1)-T_n)*(z-z_n)/(z_(n+1)-z_n);
}
end_f_loop(f,t)
}
