We present an interface fault model which is compatible with basin modeling. It considers thal the fault zone is represented by two interfaces, one for each side of the fault which is meshed conformai with its neighboring block and that can move relative! y to the other side. Combined with a Fini te Volume discretisation, this approach leads to fault-fault fluxes across fault faces that do not match. Results for one-phase and two phase flow are shown.
