Description

Computes the extent of a mesh based on the cells of the mesh. After using a module such as select_cells, it is possible to have a mesh that has nodes that are not referenced by any cell. The default values for min_vec and max_vec will use all the nodes of a mesh, including nodes no referenced by any cell. DVcompute_extent will compute min_vec and max _vec by looping over all the cells in the mesh, thus skipping the nodes that are not referenced by any cell. The output is a mesh with the new min_vec and max_vec merged in.
