Hi, I have an unstructured mesh that needs renumbering. I call METIS_MeshToNodal and then METIS_EdgeND. This gives me the perm and iperm vectors. How can I get back to the renumbering of nodes so that the matrix generated has a reduced bandwidth. Are there any examples of calling sequences. Thanks a lot. |

perm is used to identify the new node number for your originally numbering system: New node i is the perm(i) node as originally numbered. iperm is used to identify the original node number for a given new numbered node and may not be needed unless you want to continue using the original numbering for post processing, etc,. |
