What is FEFLOW?

FEFLOW is a professional software package for modeling fluid flow and transport of dissolved constituents and/or heat transport processes in the subsurface.

FEFLOW contains pre- and post processing functionality and an efficient simulation engine. A user-friendly graphical interface provides easy access to the extensive modeling options.

FEFLOW is a completely integrated system from simulation engine to graphical user interface. It also includes a public programming interface for user code.

FEFLOW is used by leading consulting firms, research institutes, universities and government organizations all over the world. Its scope of application ranges from simple local-scale to complex large-scale simulations.

FEFLOW is developed by DHI-WASY GmbH, the German branch of the DHI Group.

Thank you for a successful year 2014

Dear customers,

This year 2014 is coming to its end and the FEFLOW software team would like to thank you for the good cooperation and the trust in our software.

At the end of the year, especially around the holidays, our support is not available in the normal way. The FEFLOW Support will not be available from 22th December 2014 until 26th December 2014 and from 31th December 2014 until 01st January 2015. We will provide the service in the normal schedule from 02nd January 2015.
