Symmetric Interior Penalty Discontinuous Galerkin Discretisations and Block Preconditioning for Heterogeneous Stokes Flow
Dominic E. Charrier, Dave A. May, Sascha M. Schnepp
Provable stable arbitrary order symmetric interior penalty discontinuous Galerkin (SIP) discretisations of variable viscosity, incompressible Stokes flow utilising --$Q_{k-1…
Pipelined, Flexible Krylov Subspace Methods
Patrick Sanan, Sascha M. Schnepp, Dave. A. May
We present variants of the Conjugate Gradient (CG), Conjugate Residual (CR), and Generalized Minimal Residual (GMRES) methods which are both pipelined and flexible. These allow com…
A priori error analysis of space-time Trefftz discontinuous Galerkin methods for wave problems
Fritz Kretzschmar, Andrea Moiola, Ilaria Perugia +1
We present and analyse a space-time discontinuous Galerkin method for wave propagation problems. The special feature of the scheme is that it is a Trefftz method, namely that trial…
A Space-Time Discontinuous Galerkin Trefftz Method for time dependent Maxwell's equations
Herbert Egger, Fritz Kretzschmar, Sascha M. Schnepp +1
We consider the discretization of electromagnetic wave propagation problems by a discontinuous Galerkin Method based on Trefftz polynomials. This method fits into an abstract frame…
Optimal Control of the Inhomogeneous Relativistic Maxwell Newton Lorentz Equations
C. Meyer, S. M. Schnepp, O. Thoma
This note is concerned with an optimal control problem governed by the relativistic Maxwell-Newton-Lorentz equations, which describes the motion of charges particles in electro-mag…
Transparent boundary conditions in a Discontinuous Galerkin Trefftz method
Herbert Egger, Fritz Kretzschmar, Sascha M. Schnepp +2
The modeling and simulation of electromagnetic wave propagation is often accompanied by a restriction to bounded domains which requires the introduction of artificial boundaries. T…
