Advanced groundwater modelling

FEFLOW is the most intuitive and comprehensive software package for groundwater and porous media modelling. FEFLOW can simulate a multitude of processes involving fluid flow, groundwater age, contaminant and heat transport under fully or variably saturated conditions - from local to regional scale.

The efficient user interface and unmatched range of functionality for groundwater modelling have made FEFLOW the tool of choice for leading consultants, government organisations, universities and research institutions all over the world 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 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
