+This is the source code of the next generation OpenGeoSys.
+
+OpenGeoSys (OGS) is a scientific open source project for the development of
+numerical methods for the simulation of thermo-hydro-mechanical-chemical
+(THMC) processes in porous and fractured media. OGS is implemented in C++, it
+is object-oriented with an focus on the numerical solution of coupled multi-field
+problems (multi-physics). Parallel versions of OGS are available relying on
+both MPI and OpenMP concepts. Application areas of OGS are currently CO2
+sequestration, geothermal energy, water resources management, hydrology and 
+waste deposition.
