Looping over faces in a cell

Senthil

Hi,

I want to loop over all the faces in a cell. I used the following code. When I compile it, it says there is an error on line c_face_loop(c,t,n). error message is "non-integer subscript expression: unsigned char". I would be grateful if somebody can help me debug this code.

Thread *t,*tf; cell_t c; face_t f; int n,k;

thread_loop_c (t,d) {

begin_c_loop (c,t)

c_face_loop(c,t,n)

{

f = C_FACE(c,t,n);

tf = C_FACE_THREAD(c,t,n);

} end_c_loop (c,t) }

Thank you Senthil
