Computational issues related to iterative coupling of subsurface and channel flows. (English) Zbl 1150.76028
The authors consider iterative solution techniques for the coupling of Darcy and Stokes flow based on efficient solvers for the discrete Stokes and Darcy problems. After a short introduction into the problem and a discussion of iterative techniques used numerical examples are given in order to compare different techniques. The paper ends with a discussion of pros and cons of the techniques tested.
