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…
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…
Monolithic Multi-level Overlapping Schwarz Solvers for Fluid Problems
Stephan Köhler, Oliver Rheinbach
Additive overlapping Schwarz Methods are iterative methods of the domain decomposition type for the solution of partial differential equations. Numerical and parallel scalability o…
Combining Nonlinear FETI-DP Methods and Quasi-Newton Methods using an SQP Approach
Stephan Köhler, Oliver Rheinbach
The combination of nonlinear FETI-DP (Dual Primal Finite Element Tearing and Interconnecting) and Quasi-Newton methods using a sequential quadratic programming (SQP) approach is co…
