A Comparison of Active Flux Methods for the Vlasov-Poisson System
Lukas Hensel, Yanick Kiechle, Rainer Grauer +3
Active Flux is a third-order accurate, fairly novel finite volume method for hyperbolic conservation laws that is becoming increasingly popular. It evolves additional nodal degrees…
An asymptotic-preserving five-moment two-species plasma model coupled to an external magnetohydrodynamic solver
Magnus Deisenhofer, Aleksandr Mustonen, Simon Lautenbach +1
The paper presents an asymptotic‑preserving method that couples a two‑species five‑moment fluid plasma model to an ideal magnetohydrodynamic solver, enabling efficient global simul…
Solving the six-dimensional Vlasov-Maxwell System with Active Flux and Splitting Methods
G. Grünwald, L. Hensel, M. Deisenhofer +3
Active Flux (AF) is a modified Finite Volume method that evolves additional Degrees of Freedom (DoF) located on the cell interfaces to compute high-order approximations to the nume…
Synthetic Turbulence via an Instanton Gas Approximation
Timo Schorlepp, Katharina Kormann, Jeremiah Lübke +2
Sampling synthetic turbulent fields as a computationally tractable surrogate for direct numerical simulations (DNS) is an important practical problem in various applications, and a…
Optimal Landau-type closure parameters for two-fluid simulations of plasma turbulence at kinetic scales
Simon Lautenbach, Jeremiah Lübke, Maria Elena Innocenti +2
Two fluid simulations using local Landau-fluid closures derived from linear theory provide an efficient computational framework for plasma modelling, since they bridge the gap betw…
A split-step Active Flux method for the Vlasov-Poisson system
Lukas Hensel, Gudrun Grünwald, Katharina Kormann +1
Active Flux is a modified Finite Volume method that evolves additional Degrees of Freedom for each cell that are located on the interface by a non-conservative method to compute hi…
