+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.")
