Kiras is an Iterative, Robust, and Adaptive Schwarz Solver for Maxwell

This repository contains the Maxwell Solver KirasFM, a framework built on top of deal.II that provides all necessary tools for solving time-harmonic Maxwell's equations with an optimized Schwarz method.

Please use the Cite this repository button in the About section of this repository.

The dependencies required are deal.II, Trilinos and boost.

This CMake script installs deal.II, along with its dependencies, including Trilinos. It should be the easiest way to install deal.II with all its dependencies. For more details, see https://github.com/kinnewig/dcs2.

tl;dr:

1. Step: Download dcs2:

git clone https://github.com/kinnewig/dcs2.git
cd dcs2

1. Step: Run the install script:

./dcs.sh  -b </path/to/build> -p </path/to/install>

If you have any problems, feel free to open an issue on https://github.com/kinnewig/dcs2/issues

candi is a bash script, to install deal.II, along with all its dependencies, including Trilinos, see https://github.com/dealii/candi.

1. Download KirasFM

   git clone https://github.com/kinnewig/KirasFM.git
   

2. Compile KirasFM

   cd KirasFM
   cmake -S . -B build -D DEAL_II_DIR=</path/to/dealii>
   cmake --build build
   

By default, a simplified waveguide is selected as an example. To run the example, specify the number of subdomains that shall be used in the options.prm file. Then run the program by:

mpirun -np <number of subdomains> ./build/KirasFM

Other geometries, for example, are available through the KirasFMGridGenrator classes.
