13 The mmgs application is dedicated to surface triangulation remeshing.
14 By default it performs mesh modifications in order to control the surface
16 approximation.
17 Providing a metric file, it adapts the mesh to the prescribed sizes at
18 nodes.
19 Providing a level-set file containing the values of the level-set func‐
20 tion at the mesh nodes, the -ls option allows to explicitely mesh an
21 implicit domain.

24 1. Generic options:
25 -h Print help.
26 -v ⟨n⟩ Tune level of verbosity.
27 Takes values between -1 and 10.
28 -m ⟨n⟩ Set maximal memory size to n MBytes.
29 -d Turn on debug mode.
30 -val Print the default parameters values.
31 2. File specifications:
33 -in ⟨mesh_file⟩ Input triangulation.
34 -out ⟨output_file⟩ Output triangulation.
35 -sol ⟨solution_file⟩ Load metric file.
36 3. Parameters:
38 -ar ⟨x⟩ Angle detection.
39 -nr Disable automatic detection of sharp feature
40 (ridges, corners).
41 -hmin ⟨x⟩ Minimal mesh size.
42 -hmax ⟨x⟩ Maximal mesh size.
43 -hsiz ⟨x⟩ Constant mesh size.
44 -hausd ⟨x⟩ Control the Hausdorff distance to the under‐
45 lying surface geometry.
46 -hgrad ⟨x⟩ Control the gradation.
47 -A Enable anisotropy (without metric file).
48 -ls x Create mesh of isovalue x (0.0 if x is not
49 provided).
50 -keep-ref Preserve initial domain references when cre‐
51 ate the mesh of isovalue.
52 -nreg Normal regularization.
53 4. Additional parameters depending on compilation flags:
55 -rn ⟨n⟩ Turn on ( n=1 ) or off ( n=0 ) the renumber‐
56 ing using the SCOTCH library (only available
57 with the USE_SCOTCH compilation flag).

60 mmgs returns:
61 · the 0 value if successful;
62 · the 1 value if the process fail but we can save a conform mesh;
63 · the 2 value if the process fail and we can't save a conform mesh.
