OpenGeoSys is a free, multi-platform, scientific modeling package that enables numerical simulations of individual or coupled thermo-hydro-mechanical-chemical (THMC) processes in porous and fractured media.
The objective of the OpenGeoSys Project is to offer a platform-independent, developer-friendly as well as high-performance-oriented modeling framework with complete freedom to customise and develop its existing functionality.
A large part of the OpenGeoSys user base, from both commercial and academic organisations, works in the application fields of hydro-geology, hydrology, water resources management, geothermal energy, CO2 sequestration, waste deposition, and others.
OpenGeoSys places emphasis on incorporation of forums, social networks and benchmarking initiatives to make the project an open dialog with the user & developer community.

07.12.2016 | Leipzig | Germany

We would like to invite you to take part at the OpenGeoSys Community Meeting 2015 in Leipzig, Germany. This year, the annual meeting addresses computational methods and applications in geothermal energy use, energy storages, nuclear waste disposal, and contaminant hydrology. Furthermore it focuses on the ongoing OGS-6 development. We are looking forward to seeing you.

RELEASE 5.5.7: Iphreeqc Interface

This release includes a new Iphreeqc reaction interface to combine the individual features of both tools to simulate thermo-hydro-mechanical-chemical coupled processes with simultaneous consideration of aqueous geochemical reactions (sources only, not included in our pre-builds). Additional changes improve and extend some geometric methods like e.g. a function that closes a open-polyline if it is used to define a single surface. The bugfixing and minor extensions focus this time at the parameter transfer between geometry, mesh, boundary conditions, and source terms. For more details please have a look at the complete release notes of V5.5.7.

5-6.12.2016 | Leipzig | Germany

The porous media community will soon meet at the UFZ. Researchers working in such fields as hydrology, soil-atmosphere interaction, or geotechnical repositories from pore to field scale are welcome to share their expertise and join the meeting.The recently founded German Chapter of InterPore will hold its first meeting here at the UFZ from 5 - 6 December. The programme of the meeting and presentation abstracts are now available online. It features presentations from major German research centres active in the field and is testimony to the diversity of the society. All researchers interested in the presentations and discussion of the meeting as well as in getting involved in the society, are encouraged to join the meeting. Please visit the InterPore website to register for the event. Poster presentations can still be submitted.

image Release 5.4.05 Information Update

OpenGeoSys has been successfully applied to simulate high-temperature thermochemical heat storage devices with heterogeneous properties. The three-dimensional analyses reveal complex reaction patterns that cause high gradients in all relevant thermophysical field variables. OGS can be used to evaluate, e.g., the heat extraction behaviour under non-ideal flow conditions as well as for the definition of criteria allowing the recognition of unwanted physical changes inside thermochemical reactors during operation.
