how to find the index of the adjacent cell of one cell?
Hello,
I want to get the tempreture in the left cell next to one cell. And there are 4 faces on one cell in my grid. How can I do this with udf ? 
Thread *tf;
face_t f; cell_t c0; real x[ND_ND], xf[ND_ND]; int n; real T; C_CENTROID(x, c, t); c_face_loop(c, t, n) /* loops over all faces of a cell */ { tf = C_FACE_THREAD(c,t,n); f = C_FACE(c,t,n); F_CENTROID(xf, f, tf); if is_left_to_the_cell(x, xf) /* is the face left to the cell? */ { c0 = F_C0(f, tf); if (c0 == c) /* is itself */ c0 = F_C1(f, tf); T = C_T(c0,t); break; } } 
Than you very much !
