Numerical coupling of Navier-Stokes and Darcy flow for soil-water evaporation [article]

Christoph Grüninger, Universität Stuttgart, Universität Stuttgart
2018
The objective of this work is to develop algorithms and provide a framework for an efficient coupling of free flow and porous-medium flow to simulate porous-medium-soil-water evaporation.  ...  As the pressure has different orders in the free-flow and porous-medium-flow subdomains, the coupling is not straightforward.  ...  The convergence of these geometric multigrid methods is faster, but the implementation needs access to the grid management.  ...
