Large-scale Multigrid with Adaptive Galerkin Coarsening
Fabian Böhm, Nils Kohl, Harald Köstler +1
We propose a robust, adaptive coarse-grid correction scheme for matrix-free geometric multigrid targeting PDEs with strongly varying coefficients. The method combines uniform geome…

Large-Scale Simulations of Fully Resolved Complex Moving Geometries with Partially Saturated Cells
P. Suffa, S. Kemmler, H. Koestler +1
We employ the Partially Saturated Cells Method (PSM) to model the interaction between the fluid flow and solid moving objects as an extension to the conventional lattice Boltzmann…
