All-in-one groundwater modelling solution

Groundwater projects are becoming more and more demanding - requiring modelling software with more sophisticated capabilities than ever before. FEFLOW provides best-in-class technology for groundwater flow, contaminant, groundwater age and heat transport simulations. With its efficient user interface and its yet unmatched range of functionality and flexibility, FEFLOW has become a standard in premium groundwater modelling over the last 35 years.


  • FEFLOW is a completely integrated package from simulation engine to user interface. Maximise your productivity and limit the time and effort spent for model setup, simulation runs and results evaluation
  • Flexible meshing strategies and the option to include time-varying geometries allow for an accurate spatial representation of the geology
  • Increase reliability of your model results with FePEST, our tool for model calibration, uncertainty quantification and sensitivity analysis
  • FEFLOW is designed to handle plug-ins for extended functionality or for automating workflows. Develop your own plug-ins, or let us customise the software for you
  • It is available in different feature levels to provide the functionality that match your project. Contact us to find the licence type that suits your modelling needs
  • FEFLOW works seamlessly with the leading 3D geological modelling programs. You can easily build your geologic model in GeoModeller or Leapfrog Hydro and transfer it to FEFLOW
  • FEFLOW includes a licence for WGEO, an excellent tool for quick and easy georeferencing and processing of spatially related raster data
  • Worldwide expert user support
  • Enhance your modelling skills through high-level software training from THE ACADEMY by DHI
  • Get our expert modellers on board for your consulting projects, either as a partner, to provide extended user support, or for model and project reviews


FEFLOW is applicable for a multitude of groundwater, porous media and heat transport projects - from local to regional scale. It is the ideal software for:

  • regional groundwater management
  • groundwater management in construction and tunnelling
  • capture zone and risk assessment via groundwater-age calculation
  • mine water management
  • simulation of open-pit progress
  • saltwater intrusion
  • seepage through dams and levees
  • land use and climate change scenarios
  • groundwater remediation and natural attenuation
  • geothermal energy (deep and near surface, both open-loop and closed-loop systems)
  • groundwater-surface water interaction
  • simulation of industrial porous media
