A Massively Parallel Multigrid Method for Finite Elements

摘要

The hierarchical hybrid grid framework supports the parallel implementation of multigrid solvers for finite element problems. Specifically, it generates extremely fine meshes by using a structured refinement of an unstructured base mesh. For special problems with piecewise uniform material parameters, this leads to the possibility of using stencil-based operations, which permit a very efficient implementation of the multigrid method.
