Abstract
A multiblock approach to modelling flow in porous media allows for coupling different physical and numerical models in a single simulation through the use of mortar finite elements. The resulting non-linear algebraic system i s reduced to a non-linear interface problem which is solved by a Rill appro ximation scheme (FAS) multigrid with a Newton-GMRES smoother.
