Parallel meshing and remeshing

A parallel meshing technique using a combination between a local remeshing technique and repartitioning is presented. The meshing method is based on local mesh topology optimizations and is shown to work for all meshing applications from adaptive remeshing to mesh generation by using a minimal volume principle. Parallel remeshing is performed independently on each subdomain with fixed interfaces. A constrained repartitioning technique is introduced to move the interfaces between subdomains in an optimal way. Repartitioning and remeshing are iterated until a good mesh and a good partition are reached. Several examples are given for different meshing objectives. Application examples are shown with the commercial code Forge3, devoted to large deformation analysis and equipped with the proposed remeshing technique.
