GOLEM is a modelling platform for thermal-hydraulic-mechanical and non-reactive chemical processes in fractured and faulted porous media. GOLEM makes use of the flexible, object-oriented numerical framework MOOSE (developed at the Idaho National Laboratories), which provides a high-level interface to state of the art nonlinear solver technology. In GOLEM, the governing equations of groundwater flow, heat and mass transport, and rock deformation are solved in a weak sense (by classical Newton–Raphson or by free Jacobian inexact Newton-Krylow schemes) on an underlying unstructured mesh. Non-linear feedback among the active processes are enforced by considering evolving fluid and rock properties depending on the thermo-hydro-mechanical state of the system and the local structure, i.e. degree of connectivity, of the fracture system. More information on the governing equations, their derivation and implementation together with a list of synthetic and real case applications can be found in Cacace and Jacquey (2017) - also available from a dedicated github repository.
