Preconditioning a Fluid--Structure Interaction Problem Using Monolithic and Block Domain Decomposition Methods for the Fluid

Axel Klawonn, Jascha Knepper, Lea Saßmannshausen

A fluid-structure interaction (FSI) problem is solved via a monolithic coupling of the fluid, structure, and geometry subproblems. The iterative GMRES solver is accelerated with th…

Towards a parallel Schwarz solver framework for virtual elements using GDSW coarse spaces

Tommaso Bevilacqua, Axel Klawonn, Martin Lanser +1

The Virtual Element Method (VEM) is used to perform the discretization of the Poisson problem on polygonal and polyhedral meshes. This results in a symmetric positive definite line…

A Flow-rate-conserving CNN-based Domain Decomposition Method for Blood Flow Simulations

Simon Klaes, Axel Klawonn, Natalie Kubicki +4

This work aims to predict blood flow with non-Newtonian viscosity in stenosed arteries using convolutional neural network (CNN) surrogate models. An alternating Schwarz domain deco…

Monolithic and Block Overlapping Schwarz Preconditioners for the Incompressible Navier-Stokes Equations

Alexander Heinlein, Axel Klawonn, Jascha Knepper +1

Monolithic preconditioners applied to the linear systems arising during the solution of the discretized incompressible Navier-Stokes equations are typically more robust than precon…

Highly Scalable Two-level Monolithic Overlapping Schwarz Preconditioners for Thermo-elastoplastic Laser Beam Welding Problems

Tommaso Bevilacqua, Axel Klawonn, Martin Lanser

A thermo-elastoplastic finite element approach is used to perform the simulation of a laser beam welding (LBW) process. This results in a nonlinear, nonsymmetric saddle point multi…
