View source for Mmg 2016

== Introduction ==
'''Mmg''' is an open source software for simplicial remeshing. It provides 3 applications and 4 libraries:
* The mmg2d application and the libmmg2d library: adaptation and optimization of a two-dimensional triangulation and generation of a triangulation from a set of points or from given boundary edges
* the '''mmgs''' application and the libmmgs library: adaptation and optimization of a surface triangulation and isovalue discretization
* the '''mmg3d''' application and the libmmg3d library: adaptation and optimization of a tetrahedral mesh and implicit domain meshing
* the '''libmmg''' library gathering the libmmg2d, libmmgs and libmmg3d libraries

== Installed version(s) ==
The following versions are installed and currently available... <br/>

... on environment ''hpc-env/8.3'':

*'''Mmg/5.5.2'''-foss-2019b

== Loading / Using Mmg ==
To load the desired version of the module, use the ''module load'' command, e.g.

 module load hpc-env/8.3
 module load Mmg

Always remember: this command is case sensitive!

-opnbdy      preserve input triangles at the interface of two domains of the same reference.
-rmc   [val] enable the removal of componants whose volume fraction is less than
             val (1e-5 if not given) of the mesh volume (ls mode).
-octree val  specify the max number of points per octree cell 
-rn [n]      turn on or off the renumbering using SCOTCH [1/0]
