 *      num_nodes_g     - The number of global FEM nodes. This is output as
 *                        a NetCDF variable.
 *      num_elems_g     - The number of global FEM elements. This is output
 *                        as a NetCDF variable.
 *      num_elem_blks_g - The number of global element blocks. This is output
 *                        as a NetCDF dimension.
 *      num_node_sets_g - The number of global node sets. This is output as
 *                        a NetCDF dimension.
 *      num_side_sets_g - The number of global side sets. This is output as
