4.2 Options

As on the binary using, the Mmg3d call is done with options. This one must be specified on the tabular int opt[9]. This tabular contains:

0.

an integer defining the remeshing mode:

0	:	mesh optimization.
1	:	mesh generation in agreement with a prescribed metric,
		including points insertion/suppression and mesh optimization.
4	:	option 1 + global splitting,
		warning global splitting involves splitting of boundaries (triangles)
9	:	rigid bodies displacement and optimization (see 5).
10	:	transformation of an hexahedral/prism mesh into tetrahedral one (see 6).
-1 or -4 or -9	:	same as described previously without the optimization phase.

1.

debugging mode: 1 for debugging node, 0 if not,

2.

bucket size: default 64,

3.

the possibility to generate the mesh with applied or not edge swaps: 1 not authorizing edge swaps.

4.

the possibility to generate the mesh in keeping constant the number of nodes (no points insertion or edges supression): 1 to keep constant the number of nodes, 0 if not,

5.

the possibilty to generate the mesh with or without point relocation in optimization stage: 1 to avoid point relocation, 0 if not,

6.

verbosity level: default $3$,

7.

this integer concerns renumbering stage, it allows to tell when renumbering stage appears:
0: no renumbering stage ; 1: renumbering at beginning ; 2: renumbering after insertion stage ; 3 (default): renumbering at the beginning and after insertion stage.

8.

this integer concerns renumbering stage, it is the number of vertices by box (default 500),
