Hi all,

I'm looking for a way to retrieve temperature data along an interior boundary in a simple pipe flow. See figures 1 and 2, I would like to retrieve the temperature along the interior boundary ID 30. Figure 1 shows the location of the interior boundary, and figure 2 shows the mesh in this region. Here's my udf:

#include "udf.h"
DEFINE_ADJUST(Tint, domain)
{
real T=0;
cell_t c;
int ID = 30;
Thread *thread = Lookup_Thread(domain, ID);
begin_c_loop(c, thread)
{
T = C_T(c,thread);
printf("Température = %.4f\n", T);
}
end_c_loop(f,thread)
}

Which produces the following error messages when I start calculation:

FLUENT received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.
Error Object: #f


I understand that the temperature is defined on boundaries and cells, but not on faces where I loop. But I can't find a way to use F_C0 to get the adjacent cells temperature. I'm a rookie with C coding and I would appreciate a little help to make my udf working. It works just fine on external boundaries, but I'm missing something regarding the interior boundaries.

Thanks ahead,
François
