The aim of the project is to provide technical and numerical methods for the coupling of free flow and porous-media flow at the REV (representative elementary volume) scale. This involves the development of sophisticated methods in three basic coupling components:
(i) iterative solvers ensuring a fast convergence towards the correct solution of the coupled system,
(ii) data mapping between different discretisations used in the computational components of the simulation environ-ment, and
(iii) point-to-point communication between several parallel codes.
