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.
