Dumux code for Stokes-Darcy mortar method

This dataset contains the source code for the examples shown in Boon, W.M., Gläser, D., Helmig, R. and Yotov, I. A mortar method for the coupled Stokes-Darcy problem using the MAC scheme for Stokes and mixed finite elements for Darcy. Comput Geosci (2024). doi.org/10.1007/s10596-023-10267-6 with the open-source simulator Dumux. The first one investigates the orders of convergence with respect to the mesh size for different element types, as well as the efficiency of the interface preconditioner.

The second example simulates flow through a channel around a porous obstacle. The third one presents a porous medium with a highly heterogeneous permeability field based on the Society of Petroleum Engineers SPE10 benchmark, over which a free-flow field is simulated. The code can be used, for instance, to reproduce the results published at DaRUS.
