Introduction
To run the model, open waveguide3d.pro with Gmsh. (This is for demonstration uses only. For actual, parallel computations, you should compile GetDP and Gmsh with MPI support and run the examples from the command line on an HPC cluster.)
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, as well as new Padé-localized square-root conditions[1].
