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:
An earlier version of the code that elfe3D is based on was developed by Paula Rulff with contributions from Laura Maria Buntin and Thomas Kalscheuer at Uppsala University from 2018-2023 financed by the Smart Exploration project (European Union’s Horizon 2020 funding, grant agreement No. 775971).
The present version of elfe3D was released in 2024 under the Apache License, Version 2.0. 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.
