emsig: ElectroMagnetic Simulation in Geophysics

emsig are open-source codes to simulate electromagnetic data. Their main targets are geophysical applications (exploration and monitoring, engineering, environmental), but they are by no means limited to that. This GitHub-org contains besides the main codes also related publications for reproducibility purposes and other associated things of interest. The main website is emsig.xyz.

💻 Main code repositories

  • ▶️ empymod: Full 3D electromagnetic modeller for 1D VTI media
  • ▶️ emg3d: Multigrid solver for 3D electromagnetic diffusion
  • ▶️ libdlf: Library of Digital Linear Filters
  • ▶️ elfe3D: Modelling with the total electric field approach using finite elements in 3D
