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

FEFLOW is our software for groundwater and porous media modelling. FEFLOW enables you to simulate a multitude of processes involving fluid flow, groundwater-age, contaminant and heat transport in saturated and unsaturated porous media.

FEFLOW is the most intuitive and comprehensive software package used for groundwater and porous media modelling. FEFLOW can simulate a multitude of processes involving fluid flow, groundwater age, and contaminant and heat transport under fully or variably saturated conditions – from local to regional scale. With its efficient user interface and its unmatched range of functionality, FEFLOW has become a standard in groundwater modelling over the last 35 years.

Recommended system configuration

The recommended system configurations are:

Operating systems Fully supported operating systems *
Windows 7 Professional Service Pack 1 (64 bit), Windows 10 Pro (64 bit), Windows Server 2012 R2 Standard (64 bit) and Windows Server 2016 Standard (64 bit).Non-supported but partially tested operating systems **
Windows 8.1 Pro (64 bit) and Windows Server 2008 R2 Standard Service Pack 1 (64 bit).
Processor x64 and >= 2.2 GHz
Memory (RAM) >= 4 GB
Hard disk 5 GB of free hard disk space
Screen resolution Full HD (1920 x 1080)
Graphics adapter >= 2 GB memory, >= 24 bit colour, Shader version >= 1.30
Software requirements

* Fully supported operational systems are systems that have been tested in accordance with MIKE Quality Assurance procedures and where warranty and software maintenance agreement conditions apply.

** Non-supported but partially tested operating systems are systems, which are not officially supported by the MIKE software products. These operating systems have only undergone very limited testing for the purpose of MIKE software, but the software and key features are likely to work. Installation of MIKE software on a non-supported operating system is done so at the user’s own risk. The MIKE software warranty and software maintenance agreement conditions do not apply for unsupported operating systems and DHI is under no obligation to provide assistance or troubleshooting for cases where the software is being used on a non-supported operating system.



New feature

Extended parameter support
  • Use of user-defined expression for all material properties
  • Extended support facilities new software applications, such as Hydro-mechanical coupling for granular media, adaptation of conductivity values depeding on external factor (beside saturation), among others
Multi-document handling
  • Implementation of multiple documents handling in Python interface
More Python support
  • Support of Python 3.x
  • Support of Iron Python
  • Smart definition of observation weights
  • Weights can be set automatically depending of current observation value
  • Weights can be set automatically using FEFLOW confidence interval
Additinal support for map import/export
  • Full implementation of VTU (import / export) using Kitware package
… and much more
    Aside from these major new features, there are numerous smaller improvements. A full list can be found in the FEFLOW help system that is started by hitting when running FEFLOW or the FEFLOW Viewer.

Update 1 (7201)

Released 14 December 2018

New functionality




Record Dialog Push button “Save current time step immediately” added. Opportunity to save current timestep even if masked by custom time levels.

Fixed issues




Medium Multispecies-aware SetCoupledMassTransBndNodes() IFM API function Implementation of species-specific code for coupled B.C.
Medium Vertical 2D/3D models with mass or heat and with DNCs implied a wrong recognition of the problem class ending up with a density-dependent problem. Indeed FEFLOW checks DENS values and takes decisions if non-zero values are found. DNC parameter DENS (existence is btw doubtful) being not initialized was triggering the bug. Setting species-dependent densitiy ration zero for DNC.
Small Strange characters in message bar after mesh generation. Initialization of message buffer.
Medium Crash on startup when a plugin doesn’t implement a callback anymore. Order of deleting callbacks changed.
Medium Crash when opening layer configurator on phreatic 2D meshes. Access to TOP and BOTTOM material parameter fixed.
Medium Crash when loading ASCII DAC files greater than 2GB (Windows only). fstat() replaced by _fstat64().
Medium Crash when running simulation with unsmooth option on mixed elements meshes. Determine max number of nodes per element.
High Unsaturated-low porosity parameter is missing. (visible only in legacy files) List of visible parameters fixed.

Update 2 (7202)

Released 01 March 2019

Fixed issues

Relevance Problem Solution
Medium Invalid UTF-8 characters in IFM messages cause exceptions. Invalid UTF-8 characters are replaced by ‘?’ character.
Medium Python callback preMassSimulation and postMassSimulation don’t provide species counter. Python API fixed: def preMassSimulation(doc,species).
Medium Binary file I/O of distributes material parameter fixed. Code change.
High Crash on trying to delete a discrete element using the drop down menu in the discrete element panel Notification event changed.
High Splines functions lost Spline IDs fixed.
Medium Crashes on save from cross section view to dac Data reference fixed.
Small Considered Area always zero in Subdomain Rate Budget Cloning of face sets fixed.
Medium Limitation of max. number of user distributions to 100 Limitation removed.
Medium SOLID VOLUME FRACTION assignment lost after saving FEM file File I/O fixed.
