How to get wall boundary temperature?
Hi all
I have a problem to get wall boundary temperature. I used UDF. If I use built-in function, it's fine. That is, after calculation, if I want to know specific boundary temperature, Report > Surface Integrals > Average area weighted(or others) > specific boundary check, then, I know the boundary wall temperature. But, when I use UDF, boundary wall temperature is differ from above result. Of course, difference between two results is very small(approx. 1K), but this small difference occurs huge difference of results. I would write my UDF Code. Please tell me any idea. Thanks Bests DEFINE_ADJUST(temp_surface_up, domain) { face_t face; Thread *thread = Lookup_Thread(domain, Surface_up); /* set up domain frost thickness, 12 for frost surface ID from B.C panel */ double temp; real x[ND_ND]; /* declaration the position variable */ begin_f_loop(face, thread) { F_CENTROID(x, face, thread); temp += F_T(face, thread); } Temp_up = temp / 100; /* 100 is a number of cell along boundary */ end_f_loop(face, thread) } |
