An efficient Parallelization Approach of FEM-DDM for Large-Scale 3D Scattering Problems

摘要：

　　We present in this paper an efficient parallelization approach of the finite element domain decomposition method(FEM-DDM)for large scale 3D scattering problems.In this parallel FEM-DDM,the domain decomposition is done in a hierarchical way to minimize the inter-processor communication.In the hierarchical domain decomposition scheme,the whole FEM solution domain is first decomposed into large size subdomains with a total number equals to MPI processes.Then,each large subdomain is distributed to a MPI process and further decomposed into smaller ones to achieve good computation efficiency.Numerical examples are presented to demonstrate the accuracy,scalability,and capability of the proposed parallel FEM-DDM algorithm.
