`MMG3D`

Participant : Cécile Dobrzynski [corresponding member] .

`MMG3D` is a tetrahedral fully automatic remesher. Starting with a
tetrahedral mesh, it produces quasi-uniform meshes with respect to a
metric tensor field. This tensor prescribes a length and a direction
for the edges, thus the resulting meshes will be anisotropic meshes.
The software is based on local mesh modifications and an anisotropic
version of Delaunay kernel is implemented to insert vertex on the
mesh. Moreover, `MMG3D` allows to deal with rigid body motion and
moving meshes. When a displacement is prescribed on a part of the
boundary, a final mesh is generated such as the surface points will be
moved according this displacement. `MMG3D` is used in particular in GAMMA
for their mesh adaptation developments, but also at EPFL (maths
department), Dassault Aviation, Lemma (a french SME), etc.
`MMG3D` can be used in `FreeFem++` (http://www.freefem.org ), a free software which it enables you to solve Partial Differential Equations (PDE) easily.
