Modelling with the total electric field approach using finite elements in 3D
About:
elfe3D is a 3D forward modelling code that can simulate electric and magnetic field responses from frequency-domain controlled-source electromagnetic setups. It uses tetrahedral meshes and first-order finite-element approximations. In addition, adaptive mesh refinement approaches are implemented.
Contributions:
A first version of elfe3D was developed by Paula Rulff with contributions from Laura Maria Buntin and Thomas Kalscheuer at Uppsala University from 2018-2023.
Further developments of elfe3D by Paula Rulff, now at Delft University of Technology, are ongoing. Suggestions for improvements are welcome!

Getting started:
You find the elfe3D manual including instalation instructions in elfe3D/elfe3D/README.md
Note that, the open source mesh generator tetgen and the direct solver MUMPS must be installed additionally.
