Introduction

To run the models, open main.pro with Gmsh. (This is for demonstration uses only. For actual, parallel computations, you should compile GetDP and Gmsh with MPI support: see GetDDM).

The formulations implement non-overlapping Schwarz domain decomposition methods for the Helmholtz equation and for the time-harmonic Maxwell system. Several families of transmission conditions are implemented: zeroth- and second-order optimized conditions[1][2][3][4][5][6], new Padé-localized square-root conditions[7][8] and PML conditions. Several variants of the recently proposed double-sweep preconditioner[9] are also implemented.

For more information about these methods and the implementation, please refer to the following preprint: GetDDM: an Open Framework for Testing Optimized Schwarz Methods for Time-Harmonic Wave Problems [10].
