TIGER (Thermo-Hydro-Mechanical-Chemical sImulator for GEoscience Research) is an open-source C++ code based on the Finite Element Method. It was developed on MOOSE Framework to model complex coupled processes in fractured anisotropic heterogeneous porous media in a fully coupled and implicit manner. It is capable of modelling faults and well paths as (lower-dimensional) discrete features. This code is a part of Maziar's postdoc research, mentored by Prof T. Kohl, at the Karlsruhe Institute of Technology, Germany.
