OpenSEMBA is an open-soruce repository of codes for solving electromagnetic problems. It includes solvers based on FDTD, DGTD, MTLN, FEM and generate meshers. This repository is mainly developed and maintained by the Group of Electromagnetism of Granada (GEG) from the University of Granada (UGR). Some of these solvers are included in the Elemwave suite which provides a user-friendly interface.
