In this paper we describe the OpenGeoSys (OGS) project, which is a scientific open-source initiative for numerical simulation of thermo-hydro-mechanical/chemical processes in porous media. The basic concept is to provide a flexible numerical framework (using primarily the Finite Element Method (FEM)) for solving multi-field problems in porous and fractured media for applications in geoscience, hydrology and energy storage. To this purpose OGS is based on an object-oriented FEM concept including a broad spectrum of interfaces for pre- and postprocessing. The OGS idea has been in development since the mid-eighties and has been continuously developed in concept and software implementations evolved through FORTRAN, C, and C++. The idea behind OGS is to provide an open platform to the community, outfitted with professional software-engineering tools such as platform-independent compiling and automated benchmarking. A comprehensive benchmarking book has been published (Kolditz et al. [1]), second volume is in print. Benchmarking has been proven to be a valuable tool for cooperation between different developer teams. On one hand, object-orientation (OO) provides a suitable framework for distributed code development; however, the parallelization of OO codes still lacks efficiency. High-performance-computing efficiency of OO codes is subject to future research (Wang et al. [2]). Currently, OGS development efforts are dedicated to visual data and model integration for complex hydrological applications (Rink et al. [3])
