Elastic wave mode solver for Stimulated Brillouin calculations

The core of this program is a fully tensorial elastic mode solver implemented in open-source finite element software FEniCS. The elastic mode solve is coupled with an electromagnetic counter part to calculate all forces contributing to Brillouin gain. The source code is freely available at PySBS. If you use it please cite the appropriate paper Fully-Tensorial Elastic-Wave Mode-Solver in FEniCS for Stimulated Brillouin Scattering Modeling.
