abstract = {FROSch (Fast and Robust Overlapping Schwarz) is a framework for parallel Schwarz domain decomposition preconditioners in Trilinos. Due an algebraic approach, meaning that the preconditioners can be constructed from a fully assembled matrix, FROSch is applicable to a wide range of problems. This talk is focused on the application to nonlinear problems, including computational fluid dynamics and land ice simulations. Techniques for improving the efficiency and the use of GPU architectures are discussed.},

abstract = {Monolithic GDSW (generalized Dryja–Smith–Wildund) preconditioners are two-level Schwarz domain decomposition preconditioners for block systems. They are robust because they account for the coupling terms in the system matrix on both levels, that is, in the local and coarse problems. Block preconditioners, mostly based on block-diagonal and block-triangular preconditioners, such as the famous SIMPLE (semi-implicit method for pressure linked equations) preconditioner, often yield higher iteration counts wile coming at a lower setup cost compared to monolithic approaches. In this talk, the parallel performance of the different preconditioning techniques for incompressible fluid flow problems is investigated and compared using a finite element implementation based on the FEDDLib finite element software and Schwarz preconditioners from the Trilinos package FROSch.},
