Hi; I want to find a face (or edge in 2D) with maximum length in a cell (largest face of a cell). I want to calculate this value for all cells. How can I do this? I want to use a formulation includs maximume length of edge in each cell. Thanks

Here is a part of code that does what you want, or almost:

Thread *t; cell_t c; Domain *d; char first; int n,i; Node *node, *prev; real l, lprev;

d = Get_Domain(1);

thread_loop_c(t, d) /*loops over all cell threads in domain*/ { begin_c_loop(c, t) /* loops over cells in a cell thread */ { first = 1; found = 0; c_node_loop(c, t, n) /*loops over nodes in a cell*/ {

node = C_NODE(c,t,n);

if(1 == first)/*first node in cell*/

{

first = 0;

prev = node;

}

else

{

l = 0;

for(i = 0; i < ND_ND; i++)

l += (node->x[i]-prev->x[i])*(node->x[i]-prev->x[i]);

l = (l < lprev ? lprev : l);

lprev = l;

} } } end_c_loop(c, t) }

Is it possible to use node->x[0] for NODE_X(node)?

Yes, it is. Look through the header files and you'll find some interesting things there!
