DESCRIPTION

14     The mmg2d application is dedicated to bidimensional triangular mesh
15     remeshing.
16
17     By default it improve the mesh quality with respect to its initial size.
18     Providing a metric file, it adapts the mesh to the prescribed sizes at
19     nodes.  -ls option allows to explicitly mesh an implicit domain.
20     Without metric file, the -optim option allow to improve the mesh quality
21     with respect to the initial mesh size.

RETURN VALUES

68     mmg2d returns:
69     ·   the 0 value if successful;
70     ·   the 1 value if the process fail but can save a conform mesh;
71     ·   the 2 value if the process fail and can't save a comform mesh.
