Dear FEFLOW User,


FEFLOW 6.1 is available as a beta version effective now!  This means that our users with current SMA (Service and Maintenance Agreement) have the opportunity to familiarize themselves with the numerous new features months before the release. Don’t miss the chance to get your hands on the new version before your competitors do! With FEFLOW 6.1, the transition from the Classic to the Standard user interface is completed, and the entire range of functionality can be accessed from one graphical environment.


You have not yet used FEFLOW or you are still using the Classic interface? Now the perfect time has come to familiarize yourself with the future of groundwater modeling. We would be happy to share our knowledge with you in one of the upcoming training courses or at the 3rd International FEFLOW User Conference in Berlin, the latter providing training opportunities, but also the chance to meet with other FEFLOW users from around the world and learn about their modeling applications. Be quick – the reduced early-bird fees only apply for registrations received until the end of June!


Have you noticed that FEFLOW became a large step closer to efficient and powerful geological modeling? Close collaboration between the two respective development teams has led to a seamless integration between FEFLOW and leapfrog hydro. It has never been easier to set up complex geological models, apply them for the setup of groundwater models and feed the findings back into an updated conceptualization of the geology. Contact us if you would like to be informed more in detail about this solution or if you would like to test its cutting-edge capabilities!


Best regards,

The FEFLOW Services Team

FEFLOW 6.1 Public Beta


The release of FEFLOW 6.1 marks a significant milestone for both developers and users: For the first time it is possible to completely go without the dated classical user interface which has been used during the last 20 years. Instead, the complete workflow from mesh generation to postprocessing is done in the re-designed, modern 6.1 user interface. This will make the modeling work with FEFLOW even more productive and intuitive.

At the same time, the functional range of the software has been extended significantly.


Our developers have now brought the new software version into its final shape. Though the official release is planned for August 2012, we are happy to announce that the public beta of FEFLOW 6.1 has been released already now. Any user with a valid maintenance contract (SMA) is invited to sign up as a beta-user on


FEFLOW 6.1 beta can be run with a FEFLOW 6.0 license until the final release. We hope you will enjoy your work with the new software, which is the result of the valuable input from our users. Please persist in telling us your wishes and expectations for we will soon start working on new exciting features for future versions.


3rd International FEFLOW User Conference


The program for the 3rd international FEFLOW User Conference, taking place on September 3-5, 2012, is now online. Besides a number of interesting presentations from the various working areas of FEFLOW we will offer again a wide range of training course (FEFLOW, PEST, leapfrog hydro) and workshops prior to and after the event.


For more information visit our website Make use of the early-bird registration (deadline June 30, 2012) and sign up for the conference today!

FEFLOW and leapfrog hydro


Advanced geologic modeling capabilities are now joined with extensive groundwater modeling features.

You can easily build detailed geologic models and seamlessly transfer these to FEFLOW 6. In FEFLOW, you can solve the most demanding groundwater modeling tasks.


If you would like more information about this or the Leapfrog software suite, please visit For more information or the purchase of leapfrog hydro in addition to your FEFLOW license, please contact one of the DHI Offices or the FEFLOW Services team!
