摘要
En 中文
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.
