Hierarchical hybrid grids as basis for parallel numerical solution of PDE

Abstract

This paper describes the hierarchical hybrid grid framework, which is a storage scheme for the efficient representation and application of discrete operators and variables on globally unstructured but patch-wise regular grids. By exploiting patch-wise regularity it overcomes the performance penalty commonly associated with unstructured grids. Furthermore, it is well suited for distributed memory parallel architectures. © Springer-Verlag 2003.
