You could get the set of all Elems which are "connected" to a given node (see: build_nodes_to_elem_map() in mesh_tools.h), and then use a heuristic, e.g. the minimum connected Elem subdomain id, to "choose" a subdomain for a Node. You could then store this information as an "extra_node_integer" (see MeshBase::add_node_integer() in mesh_base.h) if desired. -- John _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
