Efficient Explicit Time Stepping of High Order Discontinuous Galerkin Schemes for Waves
Svenja Schoeder, Katharina Kormann, Wolfgang Wall +1
This work presents algorithms for the efficient implementation of discontinuous Galerkin methods with explicit time stepping for acoustic wave propagation on unstructured meshes of…
On the stability of projection methods for the incompressible Navier-Stokes equations based on high-order discontinuous Galerkin discretizations
Niklas Fehn, Wolfgang A. Wall, Martin Kronbichler
The present paper deals with the numerical solution of the incompressible Navier-Stokes equations using high-order discontinuous Galerkin (DG) methods for discretization in space.…
A performance comparison of continuous and discontinuous Galerkin methods with fast multigrid solvers
Martin Kronbichler, Wolfgang A. Wall
This study presents a fair performance comparison of the continuous finite element method, the symmetric interior penalty discontinuous Galerkin method, and the hybridized disconti…
A stabilized Nitsche cut finite element method for the Oseen problem
Andre Massing, Benedikt Schott, Wolfgang A. Wall
We propose a stabilized Nitsche-based cut finite element formulation for the Oseen problem in which the boundary of the domain is allowed to cut through the elements of an easy-to-…
A Temporal Consistent Monolithic Approach to Fluid-Structure Interaction Enabling Single Field Predictors
Matthias Mayr, Thomas Klöppel, Wolfgang A. Wall +1
We present a monolithic approach to large-deformation fluid-structure interaction (FSI) problems that allows for choosing fully implicit, single-step and single-stage time integrat…
A high-order semi-explicit discontinuous Galerkin solver for 3D incompressible flow with application to DNS and LES of turbulent channel flow
Benjamin Krank, Niklas Fehn, Wolfgang A. Wall +1
We present an efficient discontinuous Galerkin scheme for simulation of the incompressible Navier-Stokes equations including laminar and turbulent flow. We consider a semi-explicit…
