Hi all,

I am trying to use the output of a simulation using a dynamic mesh, which works fine in functional form. I save the output as float in columns of x y positions for each node. However, when I try to set the x-y values to the nodes, I get "negative volume" error.

begin_f_loop (f, tf)
{
f_node_loop (f, tf, n)
{
node_p = F_NODE (f, tf, n);

/* Update the current node only if it has not been */
/* previously visited: */
if (NODE_POS_NEED_UPDATE (node_p))
{
/* Set flag to indicate that the current node's */
/* position has been updated, so that it will not be */
/* updated during a future pass through the loop: */
NODE_POS_UPDATED (node_p);

fscanf(fp, "%f %f\n", &x, &y);

NODE_X (node_p) = x;
NODE_Y (node_p) = y;
}

}

}
end_f_loop (f, tf);
fclose(fp);

When I print out the x,y values they are correct (same as output from the original UDF)... Am I doing something wrong or this is not possible for Dynamic Mesh?
