MMGS(1) General Commands Manual MMGS(1) NAME mmgs -- Adaptation and optimization of a surface triangulation repre- senting a piecewise linear approximation of an underlying surface geom- etry. SYNOPSIS mmgs <mesh_file> [output_file] [-sol <solution_file>] [-met <metric_file>] [-h] [-v] [-m <n>] [-d] [-val] [-default] [-A] [-ar <x> | -nr] [-hmin <x>] [-hmax <x>] [-hsiz <x>] [-hausd <x>] [-hgrad <x>] [-hgradreq <x>] [-rmc x] [-ls x] [-lssurf x] [-keep-ref] [-nreg] [-xreg] [-noinsert] [-nomove] [-noswap] [-nosizreq] [-nreg] [-nsd] [-optim] [-rn <n>] DESCRIPTION The mmgs application is dedicated to surface triangulation remeshing. By default it performs mesh modifications in order to control the sur- face approximation. Providing a metric file, it adapts the mesh to the prescribed sizes at nodes. -optim option allows to improve the mesh quality with respect to ini- tial mesh size and the surface approximation respect. Providing a level-set file containing the values of the level-set func- tion at the mesh nodes, the -ls option allows to explicitely mesh an implicit domain and the -lssurf option splits boundary edges of the mesh on a provided isovalue. COMMAND LINE ARGUMENTS 1. 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. -default Write a local parameter file (with exten- sion .mmgs) with setted values. -val Print the default parameters values. 2. File specifications: -in <mesh_file> Input triangulation. -out <output_file> Output triangulation. -sol <solution_file> Load metric or level-set file. -met <metric_file> Load metric file in level-set mode. 3. Mode specifications (default is mesh adaptation): -ls x Create mesh of isovalue x (0.0 if x is not provided). -lssurf x Split boundary edges on isovalue x (0.0 if x is not provided). 4. Parameters: -A Enable anisotropy (without metric file). -ar <x> | -nr Threshold for angle detection or sharp features detection disabling. -hmin <x> Minimal mesh size. -hmax <x> Maximal mesh size. -hsiz <x> Constant mesh size. -hausd <x> Control the Hausdorff distance to the un- derlying surface geometry. -hgrad <x> Control the gradation. -hgradreq <x> Control the gradation from required enti- ties toward others. -rmc x Remove componants whose volumic fraction is less than x (1.e-5 if x is not pro- vided) of the whole mesh volume or not connected to base references provided in parameter file (level-set mode). -keep-ref Preserve initial domain references when create the mesh of isovalue. -noinsert No point insertion/deletion. -nomove No point relocation -noswap No edge or face flipping. -nosizreq No imposition of the size of required edges over required vertices. -nreg Normal regularization using laplacian - antilaplacian smoothing. -xreg Vertex coordinates regularization using laplacian - antilaplacian smoothing. -nsd <n> Save the subdomain of index n (default is n=0 which save all subdomains). -optim Mesh improvement with respect to the ini- tial mesh size. -rn <n> Turn on ( n=1 ) or off ( n=0 ) the renum- bering using the SCOTCH library (only available with the USE_SCOTCH compilation flag and if the scotch library is founded). RETURN VALUES mmgs returns: • the 0 value if successful; • the 1 value if the process fail but we can save a conform mesh; • the 2 value if the process fail and we can't save a conform mesh.
