# Installation

1D and 2D simulations are realized with an external software for hydrogeological flow and transport in porous environnement.

Two softwares are currently connected to THYRSIS:

- OPENFOAM, through the (opensource) porousMultiphaseFOAM toolbox [HSF+15].

- METIS (Modélisation des Écoulements et des Transports avec Interaction en milieu Saturé), developed by the Ecole des Mines de Paris [Gob89].

The simulation software is chosen by using the THYRSIS Preferences dialog.
