Hi all

I am a UDF & Fluent beginner. Now, I focus the conjugate heat problem.

I am studying the 2D channel flow with conduction from channelís wall.
My objective, I needed to know the heat flux in x direction (streamwise), and then I created a interior boundary condition (edge). And I knew the zone ID number.

This interior line could show me a temperature profile; then I was using the lookup_thread (thread pointer to ID zone) for showing the temperature every iteration.

Problem is that in an example, it can show the coordinate x, y, but I need to see the temperature on my specific zone ID. I really need someone to help me.

Thanks in advance.

This is the code

#include "udf.h"


DEFINE_ADJUST(print_f_centroids, domain,t)
{
real FC[2];
face_t f;
int ID = 11;
Thread *thread = Lookup_Thread(domain, ID);
begin_f_loop(f, thread)
{
F_CENTROID(FC,f,thread);
printf("x-coord = %f ,y-coord = %f \n",FC[0], FC[1]);
}
end_f_loop(f,thread)
}
