Hi guys, I am writing a udf to determine the temperature at wall by applying constant heat flux across the wall. There is flow across the channel, and the model is in 2d. And I trying to write it between the cell centroids. Since it's at the wall, which means only c0 is available. I am new to udf, so I am not sure how I could implement the code correctly. Any suggestion would be great! thank you!


#include "udf.h"
#include "sg.h"
DEFINE_PROFILE(wall_temperature,t,i)
{
real A[ND_ND];
real ds, q, k, A_by_es;
face_t f;
cell_t c0;
Thread *t0;
real es[ND_ND];
real dr0[ND_ND];


q=500;
k=0.6;

begin_f_loop(f,t)
{
c0 = F_C0(f,t);
t0 = F_C0_THREAD(f,t);
BOUNDARY_FACE_GEOMETRY(f,t,A,ds,es,A_by_es,dr0);
F_PROFILE(f,t,i)=-q*k*ds + C_T(c0,t0);
}
end_f_loop(f,t)
}

code is correct, however, your approach is not clear
