Two-derivative deferred correction time discretization for the discontinuous Galerkin method
Jonas Zeifang, Jochen Schuetz
In this paper, we use an implicit two-derivative deferred correction time discretization approach and combine it with a spatial discretization of the discontinuous Galerkin spectra…
Jacobian-free explicit multiderivative Runge-Kutta methods for hyperbolic conservation laws
Jeremy Chouchoulis, Jochen Schütz, Jonas Zeifang
Based on the recent development of Jacobian-free Lax-Wendroff (LW) approaches for solving hyperbolic conservation laws [Zorio, Baeza and Mulet, Journal of Scientific Computing 71:2…
Parallel-in-time high-order multiderivative IMEX solvers
Jochen Schütz, David C. Seal, Jonas Zeifang
In this work, we present a novel class of parallelizable high-order time integration schemes for the approximate solution of additive ODEs. The methods achieve high order through a…
A novel regularization strategy for the local discontinuous Galerkin method for level-set reinitialization
Fabian Föll, Christoph Müller, Jonas Zeifang +1
In this paper we propose a novel regularization strategy for the local discontinuous Galerkin method to solve the Hamilton-Jacobi equation in the context of level-set reinitializat…
A Neural Network based Shock Detection and Localization Approach for Discontinuous Galerkin Methods
Andrea D. Beck, Jonas Zeifang, Anna Schwarz +1
The stable and accurate approximation of discontinuities such as shocks on a finite computational mesh is a challenging task. Detection of shocks or strong discontinuities in the f…
