lmin and lmax are normal arrays of length 3. In Fortran, you don't access lmin(0). > and lmin(1), lmin(2), and lmin(3) are for x, y, and z dimension, > respectively. And the returned value is index (local node index in x, > y, z dim), not the coordinate. Correct? It is the coordinate value, assuming you have set DMSetCoordinates.
