Waveform Relaxation with asynchronous time-integration
Peter Meisrimel, Philipp Birken
We consider Waveform Relaxation (WR) methods for partitioned time-integration of surface-coupled multiphysics problems. WR allows independent time-discretizations on independent an…

Conservative iterative methods for implicit discretizations of conservation laws
Philipp Birken, Viktor Linders
Conservation properties of iterative methods applied to implicit finite volume discretizations of nonlinear conservation laws are analyzed. It is shown that any consistent multiste…

Quasi-Newton Waveform Iteration for Partitioned Fluid-Structure Interaction
Benjamin Rüth, Benjamin Uekermann, Miriam Mehl +3
We present novel coupling schemes for partitioned multi-physics simulation that combine four important aspects for strongly coupled problems: implicit coupling per time step, fast…
