RELEASE 5.5.7: Iphreeqc Interface

The OGS tutorial Computational Geotechnics – Storage of Energy Carriers is now avaliable. Here is a small excerpt from the preface:

In particular, this book presents an introduction to thermo-mechanical modelling of gas storage in salt caverns using OGS. The material is mainly based on work done in the framework of the ANGUS+ and NUMTHECHSTORE projects, and is also the result of a close cooperation within the OGS community. These voluntary contributions are highly acknowledged.

This is the fourth tutorial published in the SpringerBriefs series Computational Modeling of Energy Systems. The series is open to contributions addressing advanced computational and theoretical methods, tools, and frameworks for the design, analysis, optimization, and assessment of a diverse range of energy technologies and systems. Further information, available here).

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. 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.

RELEASE 5.4.05: 3D Simulations of Non-Equilibrium Thermochemical Processes in Heterogeneous Systems

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.

Release Notes

OGS Prototype New kernel and data structures

A first prototype of the 6th version of OpenGeoSys is off the ground. After single and coupled FORTRAN modules in ROCKFLOW 1+2, the C version 3 with dynamic data structures, the object-oriented C++ parallelized version 4, completed with data integration and some visualization tools by version 5; ogs6 is aimed at performing on supercomputing platforms and providing complete workflows for solving of coupled multi-field problems in real world applications. The major paradigms of ogs6 are being developer-friendly, performing, and user-friendly. Interested? Then have a look here:
