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. + +## Important links: + +- Getting started tutorial: http://docs.opengeosys.org/docs/quickstart +- Descriptions of selected benchmarks: http://docs.opengeosys.org/docs/benchmarks + +- Source code access: https://github.com/ufz/ogs +- Developer guide: http://docs.opengeosys.org/docs/devguide + +## 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 + +## 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 + - OGS#PETSc interface for parallel computing (02/2015*planned) + - Neuman boundary conditions (03/2015*planned) + +### Planned + - Parabolic solver
