Two-level substructuring and parallel mesh generation for domain decomposition methods

Parallel Dynamic Mesh Generation and Domain Decomposition

The mapping of computations to parallel machines can be realized at the various data structures associated with the computations. In the case of PDE (Partial Differential Equations) based applications, we decided to fonnulate this problem at the discrete data structures of the underlying computation [Chri 91]. In this paper, we fonnulate and implement parallel mapping algorithms on distributed ...

MDEC: MeTiS-based Domain Decomposition for Parallel 2D Mesh Generation

Domain decomposition methods are commonly employed within the context of parallel numerical algorithms. Most often, the domain decomposition is performed before the main computation begins. Within the context of mesh generation, parallel mesh generation is desired when the goal is to mesh a very large geometric domain or if very high accuracy is required. In this paper, we propose a novel techn...

Substructuring domain decomposition scheme for unsteady problems

Domain decomposition methods are used for approximate solving boundary problems for partial differential equations on parallel computing systems. Specific features of unsteady problems are taken into account in the most complete way in iteration-free schemes of domain decomposition. Regionally-additive schemes are based on different classes of splitting schemes. In this paper we highlight a cla...
