Four-Level Overlapping Schwarz as Multigrid Coarse Solver for Incompressible Non-Newtonian Flow in Complex Geometries
Stephan Köhler, Oliver Rheinbach
For complex geometries, the coarse problem of geometric multigrid can be too large to be solved by a direct solver. Here, we report on the use of domain decomposition applied to th…

Overlapping Schwarz Preconditioners for Pose-Graph SLAM in Robotics
Stephan Köhler, Oliver Rheinbach, Yue Xiang Tee +1
We investigate scalable two-level overlapping Schwarz domain decomposition methods with energy-minimizing coarse spaces of GDSW type (Generalized Dryja--Smith--Widlund type) as pre…
