GetDDM: An open framework for testing optimized Schwarz methods for time-harmonic wave problems

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We present an open finite element framework, called GetDDM, for testing optimized Schwarz domain decomposition techniques for time-harmonic wave problems. After a review of Schwarz domain decomposition methods and associated transmission conditions, we discuss the implementation, based on the open source software GetDP and Gmsh. The solver, along with ready-to-use examples for Helmholtz and Maxwell’s equations, is freely available online for further testing. Title of program: GetDDM Catalogue Id: AEZZ_v1_0 Nature of problem Computing the solution of large scale time-harmonic acoustic and electromagnetic wave problems. Versions of this program held in the CPC repository in Mendeley Data AEZZ_v1_0; GetDDM; 10.1016/j.cpc.2016.02.030本程序源自贝尔法斯特女王大学（1969-2018）所持有的CPC程序库。本文档介绍了一个名为GetDDM的开源有限元框架，旨在测试针对时谐波动问题优化的Schwarz区域分解技术。在回顾Schwarz区域分解方法及其相关传输条件之后，我们讨论了基于开源软件GetDP和Gmsh的实现。该求解器及其适用于亥姆霍兹方程和麦克斯韦方程的现成示例，均可免费在线获取，以供进一步测试。 程序标题：GetDDM 目录编号：AEZZ_v1_0 问题性质：计算大规模时谐声学和电磁波问题的解。 Mendeley Data CPC存储库中该程序的版本：AEZZ_v1_0; GetDDM; 10.1016/j.cpc.2016.02.030
