You can now access FEFLOW on Azure Marketplace, where you can start modelling in the cloud with no hardware limitation in four simple steps. Learn more.

Use your FEFLOW models for groundwater allocation, wellhead protection, water volume estimation, water origin analysis and well-field optimisation. Model groundwater/surface water interaction, contamination risks, calculate travel time, analyse catchment zones, capture zone delineation and managed aquifer recharge.

Model all relevant components of heat transport processes including near surface geothermal installations, deep geothermal installations, open and closed loop systems, borehole heat exchangers (BHE), heat exchanger arrays and aquifer thermal energy storage (ATES). Simulate the heat transport in porous and fractured media under saturated and unsaturated conditions including the interaction with heating and cooling installations. Learn more

You can easily build your geologic model in GeoModeller 3D, GOCAD or Leapfrog Hydro and transfer it to FEFLOW.

Model mine dewatering and perform seepage analysis, simulate pit-lakes, forecast possible effects of mine flooding, assess pumping schemes and estimate water volume. Design containment and clean-up strategies for contaminants released in the process. Forecast the effects of mine flooding after abandonment.

Accurately estimate seepage amounts in mining environments to reach expected dewatering volumes and time. Model leakage problems from tailings or earth dams, underground pipe networks or underground waste storage tanks. Benefit from automatic seepage assignment, the possibility to include intermittent seepage stages and cutting edge visualisation tools to identify the location and direction of seepage. Identify unknown seepage locations, analyse seepage conditions or form containment approaches to mitigate seepage.

Assess groundwater contamination for one or multiple chemical species. Define well-head protection zones, simulate groundwater flow paths and perform capture zone delineation for pump and treat systems. Conduct reactive transport modelling including kinetic reactions and equilibrium sorption. Perform risk analyses including best and worst case scenarios. Learn more

Only FEFLOW provides a unique set of tools for calculating groundwater age, lifetime expectancy and exit probability.This enables you to easily and precisely answer vital questions in aquifer and well-field analysis.

Perform capture zone analysis of travel time, the remaining time within a specific water body before exiting the model, catchment zones and water origin within each individual capture zone. Perform spatio-temporal optimisation of water resources such as pumping schemes and use of artificial recharge and estimate the water volume required to maintain demanded balances. Model the hydraulic connections between different water systems such as surface water and groundwater as well as different groundwater systems and mixing processes of different water sources, such as fresh water and old saline/brackish groundwater. Learn more

Model coastal saltwater intrusion processes, upconing processes below production wells, contamination and remediation and freshwater storage in saline aquifers. Learn more

All FEFLOW packages include FePEST – a convenient graphical interface for using PEST by John Doherty with FEFLOW models. It facilitates the setup process and gives immediate graphical feedback on the calibration process and more. Also, parameter estimation or uncertainty analysis tasks can be executed in parallel on many computers. Recent FePEST updates expand the calculation capabilities with its built-in cloud parallelisation with Azure services.

FEFLOW is designed to handle plug-ins for extended functionality. A convenient programming interface makes plug-in development a manageable task – even for less experienced programmers. A number of plug-ins for specific needs are readily available.

FEFLOW provides access to almost all its methods through a FEFLOW–Python interface. This interface accelerates daily modelling workflows from pre-processing (material parametrization) until post-processing (automatic export of results, creation of impressive graphics with Python libraries, etc.).

FEFLOW is fast and designed to handle small and extremely large models alike. There are no limits on model size and FEFLOW employs parallel execution on multicore systems. Matrix solvers include the fast algebraic multigrid solver, SAMG, and the parallel direct solver, PARDISO.

FEFLOW supports a broad variety of 2D and 3D map data formats for visualisation and data import. In addition to standard file formats, such as ASCII text and MS Excel, dxf and shp, it also supports live connections to local or remote spatial database systems and the import from modern geological software (e.g. Leapfrog, GeoModeller 3D, GOCAD etc.).

FEFLOW‘s physical basis and internally used methods are transparently described in extensive documentation. All parts of the FEFLOW simulation engine have passed extensive benchmark testing against analytical solutions, physical laboratory test results and results from other well-known simulation systems.

In viewer mode, FEFLOW’s advanced visualisation and post-processing capabilities are available free of charge. Model reviewers and clients no longer need a software licence to evaluate input data and simulation results.
