mmg2d — Adaptation and optimization of bidimensional meshes

Synopsis

mmg2d ⟨mesh_file⟩ [output_file] [-sol ⟨solution_file⟩] [-mov ⟨moving_file⟩] [-h] [-v] [-m ⟨n⟩] [-d] [-val] [-ar ⟨x⟩] [-nr] [-hmin ⟨x⟩] [-hmax ⟨x⟩] [-hsiz ⟨x⟩] [-hausd ⟨x⟩] [-hgrad ⟨x⟩] [-lag ⟨n⟩] [-ls x] [-nsd ⟨n⟩] [-msh ⟨n⟩] [-degrad ⟨Qw Qdeg⟩] [-optim] [-noswap] [-nomove] [-noinsert]

Description

The mmg2d application is dedicated to bidimensional triangular mesh remeshing.

By default it improve the mesh quality with respect to its initial size.
Providing a metric file, it adapts the mesh to the prescribed sizes at nodes. -ls option allows to explicitly mesh an implicit domain.
Without metric file, the -optim option allow to improve the mesh quality with respect to the initial mesh size.

Command Line Arguments

Generic options:
-h
Print help.
-v ⟨n⟩
Tune level of verbosity.
Takes values between -1 and 10.
-m ⟨n⟩
Set maximal memory size to n MBytes.
-d
Turn on debug mode.
-val
Print the default parameters values.
File specifications:
-in ⟨mesh_file⟩
Input triangulation.
-out ⟨output_file⟩
Output triangulation.
-sol ⟨solution_file⟩
Load metric file.
-mov ⟨moving_file⟩
Load displacement file (only with the -lag option).
Parameters:
-ar ⟨x⟩
Angle detection.
-nr
Disable detection of sharp features (ridges, corners).
-hmin ⟨x⟩
Minimal mesh size.
-hmax ⟨x⟩
Maximal mesh size.
-hsiz ⟨x⟩
Constant mesh size.
-hausd ⟨x⟩
Control the Hausdorff distance to the underlying surface geometry.
-hgrad ⟨x⟩
Control the gradation.
-lag ⟨n⟩
Lagrangian mesh displacement according to mode 0 ( n=0 ), 1 ( n=1 ) or 2 ( n=2 ).
-ls x
Create mesh of isovalue x (0.0 if x is not provided).
-optim
Mesh improvement with respect to the initial mesh size.
-noswap
No edge or face flipping.
-nomove
No point relocation
-noinser.
No point insertion/deletion.
-nsd ⟨n⟩
If the mesh don't have triangles, save the subdomain number n (set n=0 to save all subdomains).
-msh ⟨n⟩
Write and/or read mesh files at the gmsh file format. Save the mesh at gmsh format if val=1. Read and write the meshes at the gmsh format if val=2.
-degrad ⟨Qw Qdeg⟩
Optimization thresholds for the -lag option.

Return Values

mmg2d returns:

the 0 value if successful;
the 1 value if the process fail but can save a conform mesh;
the 2 value if the process fail and can't save a comform mesh.
