**renumbering#

Description#

This command renumbers the mesh so that the global matrix front or bandwidth will be reduced. The algorithm is a modified Sloan renumbering scheme. The renumbering by this command is not especially fast, and cannot directly handle disconnected mesh regions. In order to renumber across contact or MPC linked regions, use the **make_springs command.

Note

It is advisable to do this operation as the last mesher command before saving the mesh. Alternately on UNIX platforms the Zrenum command can be used.

Note

The sparse matrix solvers should employ the metis renumbering, or use built-in renumbering if available for the solver used.

Syntax#

**renumbering   [ *frontal ]   [ *nodal ]   [ *w1 val ]   [ *w2 val ]   [ *subdomain ]

*frontal

Renumbers elements to reduce the front size in a frontal solution.

*nodal

Renumbers nodes to reduce the bandwidth size in a banded matrix solution (skyline).

*subdomain

Renumbers according to subdomains for optimizing parallel computations.
