All-in-one groundwater modelling solution

Simulate a multitude of groundwater processes involving flow, contaminants, groundwater age and heat transport under fully or variably saturated conditions.

Why FEFLOW?

Cover a broad variety of processes on the surface and in the subsurface

FEFLOW is the only tool you need for integrated modelling of all relevant flow and mass transport processes. It can be coupled with other MIKE products to simulate surface water as well as its interaction with groundwater for inundation studies and flood risk assessments. Analyse what’s below the surface through simulation of underground structures, tunnels and other types of excavation.

With FEFLOW, the decision support opportunities are limitless

Mining

Model groundwater flow, assess seepage amounts and estimate pore pressure profiles to support open pit slope and underground mining design. Create dewatering and worst-case scenarios, assess the hydraulic performance of a tailings storage facility and simulate the fate of contaminants for EIAs.

Engineering

Assess groundwater remediation strategies for construction and tunnelling projects. Simulate the geometrical changes of the tunnel, undergrounds and other settings involving excavations.

Water Resources

Identify potential groundwater abstraction locations and optimise scenarios of Managed Aquifer Recharge (MAR). Analyse saltwater intrusion in freshwater resources and understand groundwater-surface water interaction (including fully hydrodynamical solutions).

Water Quality

Use the built-in Kinetics Editor to account for transport processes from conservative, reactive and multi-species. Couple groundwater modelling with external models to simulate land use impacts on groundwater quality at the regional scale. Assess the impact and design of nuclear waste storage facilities.

Geotechnical Engineering

Design and implement a leakage mitigation effort and address related potential dam failure modes. Estimate spatial-temporal changes of pore pressure based on fully 3D Richards-based solution.

Industrial

Maximise the efficiency of consumer products and develop innovative technologies and new designs. Create highly detailed 3D visualisation of the infiltration and storage processes, predict absorption behaviour and optimise absorber materials with varying geometry and physical properties

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. FePEST recent implementation expand the calculation capabilities with its built-in cloud parallelization 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 PARDISO parallel direct solver. 3D groundwater models are computationally demanding. Thus, FEFLOW employs optimised numerical solvers, for example by making use of parallel computing on multiprocessor and multicore machines.

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

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.

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