**metis_renumbering#
Description#
This is a re-numbering mesher which will reduce the fill-in generated during factorization of the global matrix with sparse direct solvers (sparse_direct or sparse_dscpack). The software is based on the Metis package developed by the Computer Science Department at the University of Minnesota, and used by permission. Information on the Metis package is available on the Web at the link: http://www-users.cs.umn.edu/~karypis/metis/
Note
Since version 8.3 the nodal renumbering for sparse matrices is done automatically, so this command is no longer generally used.
Syntax#
The command has the following syntax:
**metis_renumbering
\(~\,\) [ *param_files file1 … fileN ]
\(~\,\) [ *end_with nset1 … nsetN ]
*param_filesenables to renumber in the same time external parameter files.
*end_withrenumber a list of node sets at the end. For contact simulations, it is common practice to renumber nodes in a way that nodes that are expected to come into contact are assigned consecutive or nearby node numbers.
