Outline of the algorithm

This page describes the main steps of the ParMmg algorithm.

1. Mesh distribution

Centralized meshes are colored and distributed among available processors.

2. Mesh subdivision

On each processor, the mesh is subdivided into sub-meshes of size optimal for the sequential remesher.

Initial mesh subdivision into submeshes

3. Remeshing

The sequential remesher is called on each sub-mesh whose interfaces have been freezed.

Sequential remeshing of each group with freezed interfaces

4. Interface migration

In order to be able to remesh the constrained interfaces, we create new sub-meshes using a front migration algorithm: now, the old freezed interfaces must be inside the sub-meshes.

5. Mesh evaluation/Stop criterion

If the mesh is not "perfect" goto 3. else goto 6.

6. End of the algorithm
