On the convergence and efficiency of splitting schemes for the Cahn-Hilliard-Biot model
Cedric Riethmüller, Erlend Storvik
In this paper, we present a novel solution strategy for the Cahn-Hilliard-Biot model, a three-way coupled system that features the interplay of solid phase separation, fluid dynami…

Data-driven geometric parameter optimization for PD-GMRES
Lennart Duvenbeck, Cedric Riethmüller, Christian Rohde
Restarted GMRES is a robust and widely used iterative solver for linear systems. The control of the restart parameter is a key task to accelerate convergence and to prevent the wel…

Partitioned Coupling vs. Monolithic Block-Preconditioning Approaches for Solving Stokes-Darcy Systems
Jenny Schmalfuss, Cedric Riethmüller, Mirco Altenbernd +2
We consider the time-dependent Stokes-Darcy problem as a model case for the challenges involved in solving coupled systems. Keeping the model, its discretization, and the underlyin…
