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…

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…

Thermodynamically consistent phase-field modeling and numerical simulation for reactive two-phase fluid-solid dynamics
Cedric Riethmüller, Cedric Riethmüller, Lars von Wolff +3
We introduce a coupled Cahn-Hilliard Navier-Stokes model that governs the reactive two-phase dynamics of a system that consists of a fluid and a solid phase and prove its thermodyn…
