The 6th version of OpenGeoSys (OGS) is under way. 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 visualization tools by version 5; ogs6 - as an open source project - 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.

Release notes
The first version ogs6 is dedicated for elliptic problems.
Features
- Basic structures of processes
- Mathematical operations are based on Eigen3 library
- Linear solvers: DenseMatrix with Gauss elimination, and LIS (<http://www.ssisc.org/lis/>)
- XML based IO
- Standard finite element method (FEM)
- Available element types: lines, triangles, quads, hexahedra
- Dirichlet boundary conditions
- Linear elliptic solver (e.g. Groundwater flow) for scalar quantities in homogeneous media
Fixes
- DenseMatrix Gauss algorithm pivoting
- Fixing mem-leaks on DataExplorer start up
- Fixing resizing and layout issues in various DataExplorer dialogs
Test examples
- Example 1: Unit square (access)
- Example 2: Unit cube (access): has 1000 hexahedra elements with Dirichlet boundary conditions (u=1|x=0) and (u=-1|x=1)
Next steps
In development
- OGSPETSc interface for parallel computing (02/2015*planned)
- Neuman boundary conditions (03/2015*planned)
Planned
