News

The comprehensive book “FEFLOW – Finite Element Modeling of Flow, Mass and Heat Transport in Porous and Fractured Media” written by H.J. G Diersch will officially be released by Springer in late summer. Hans-Jörg G. Diersch has started the development of FEFLOW in academia in 1979. During the 1990s he has successfully ventured into the commercial software market; to date he forms part of the now much larger development team, serving as its senior scientific advisor.

The book is intended to put advanced theoretical and numerical methods into the hands of modeling practitioners and scientists. It starts with some general theory for all relevant flow and transport phenomena on the basis of the continuum approach, systematically develops the basic framework for important classes of problems (e.g. multiphase/multispecies non -isothermal flow and transport phenomena, unsaturated-saturated problems, free-surface groundwater flow, aquifer-averaged equations), introduces finite-element techniques for solving the basic balance equations, discusses in detail advanced numerical algorithms for the resulting nonlinear and linear problems and completes with a number of benchmarks, applications and exercises implemented in FEFLOW to illustrate the different types of problems.

Software News

Plug-in for the Design of Open-Loop Geothermal Systems

A plug-in for the design and optimization of open-loop geothermal systems is now part of the new patch FEFLOW 6.108 which is available for download on our website.

The plug-in is designed for applying a time-varying heating or cooling power demand between groups of abstraction and injection boreholes for open-loop geothermal systems. Taking into account basic heat-pump and heat-exchanger properties, it calculates the minimum required fluid flow through the borehole system based on defined injection temperatures which may be fixed (separately for heating/cooling phases) or varying with extraction temperature.

The resulting flow rates and temperature differentials can be monitored in charts, and warning messages indicate situations when the power demand cannot be fulfilled. All relevant data can also be logged to text files during the simulation.

To use the plug-in, simply update your FEFLOW version to the latest patch (FEFLOW 6.108). The plug-in will automatically be displayed in the list of available plug-ins in the Plug-ins panel.

FePEST

FePEST can still be considered to be in BETA status but we have implemented a number of enhancements since the last version.

FePEST which comes with the new patch FEFLOW 6.108 now provides radial basis functions as interpolation method for pilot points. Further enhancements regarding pilot-point functionality include the option to add a buffer around the target area or zone for pilot-point generation which leads to better interpolation results at the edge of the zones. Furthermore, transient problem types with multiple options are now supported.

FEFLOW 6.2

While the release of our next version FEFLOW 6.2 is still some time away, we feel that some of the new features and tools are already worth a first glimpse.

Random walk visualization

A new quality of flow-field visualization in FEFLOW becomes possible by making available the random-walk method for particle tracking. Employing this method, virtual particles can be subjected not only to advection (i.e., the velocity field) but to diffusion and dispersion as well. The result can be a much more informative representation as shown in the example above.

Measure Tool

 

Judging from the number of requests we received, the new measure tool should be a welcome addition for many users. As the snapshots illustrate, the tool provides a convenient means to easily measure path lengths as well as enclosed areas within your FEFLOW models.

Events

FEFLOW at MODFLOW and More 2013
2-5 June 2013

The DHI Groundwater Modelling Centre will again attend this year’s MODFLOW and More groundwater conference in Golden (Colorado, USA) with a presentation and an exhibition booth.

We expect that the recent release of MODFLOW USG (http://water.usgs.gov/ogw/mfusg/ ) will be the dominating topic at the meeting, and we acknowledge its significance for giving MODFLOW users an option to go beyond the tight geometric restrictions associated with traditional finite-difference grids. We look forward to many more groundwater modelers being introduced to the advantages of unstructured meshes – the core principle of spatial discretization in FEFLOW from its beginning more than three decades ago.

The conference will be followed by a 2-days FEFLOW short course (June 6-7). The course will provide an introduction to modeling complex flow and transport processes in the subsurface. Possible topics include groundwater flow, contaminant and reactive transport, heat transport, density-dependent flow and unsaturated or variably saturated flow. In addition, you will gain first-hand experience in model set-up, simulation run and postprocessing with FEFLOW 6.1

All course details can be found here. Registration is possible on the IGWMC webpage.

FEFLOW 'Down Under' User Group Meeting 2013
19-21 June 2013

DHI is inviting interested colleagues to attend the 2nd Australian and New Zealand FEFLOW User Group Meeting being held in Adelaide on 19-20 June, 2013. The meeting will feature numerous opportunities for exchanging ideas, improving your knowledge and extending your simulation skills in the application of FEFLOW.

The meeting will consist of two days of presentations including keynotes from leading industry speakers as well as the FEFLOW 6.1 development team, highlighting the new capabilities of FEFLOW and explaining future development directions.

In a compact 1-day training course, we will share our knowledge with users wanting to fast track their skill development in FEFLOW 6.1, PEST and MIKE SHE.

For more information and registration, please contact our Customer Care Unit, DHI Australia or use our registration form.

Summer School in Berlin
23-27 September 2013

It’s becoming a tradition: The week-long summerschool program Modelling of Mass and Energy Transport in Porous Media With Practical Applications is again offered this year. The summer school is a collaborative effort between DHI-WASY, Freie Universität Berlin and Geoforschungszentrum Potsdam.  At a very affordable price, it offers a combination of lectures, introductory FEFLOW exercises, and FEFLOW application in project work.

Click here to view all details for the summerschool.

DHI-WASY will also participate in:

IMWA 2013 Annual Conference in Golden (CO), USA
5-9 August 2013

40th IAH International Congress in Perth, Australia
15-20 September 2013

Past Events

Geothermal Workshop in Turkey

On March 20 and 21, DHI-WASY held a workshop on “Geothermal modeling using FEFLOW” in collaboration with the Izmir Institute of Technology - Geothermal Energy Research and Application Center in Izmir/Turkey. Professionals from public, academic and private sectors in Turkey and neighboring countries attended this workshop to discuss latest developments in the geothermal energy sector in Turkey and on hydrothermal modeling within porous and fractured media using FEFLOW.

In addition, the workshop accommodated a 1-day FEFLOW training course which covered the basics of groundwater-flow modeling and advanced topics addressing shallow and deep geothermal energy systems.

We would like to thank all participants for the very successful workshop. In particular we would like to express our gratitude to Dr. Alper BABA (Izmir Institute of Technology - Geothermal Energy Research and Application Center) for the excellent collaboration and organization of the workshop.

Successful FEFLOW Training in Japan

From 22-26 April 2013, 12 motivated and skilled professionals from public, academic and private sectors in Japan attended a five days detailed FEFLOW course. The comprehensive training course was held in Yokohama and was provided by Julia Mayer from DHI-WASY and by DHI Japan.

The training covered basic and advanced topics with a special focus on geothermal issues. Other topics included FEFLOW 6.1 usage and hints, unsaturated flow, density-dependent flow, fracture flow and chemical reactions.

We would like to thank all participants for their positive feedback and for a very successful week.
