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
Accurately modeling collisionless space plasmas requires capturing small-scale kinetic effects while keeping global-scale simulations computationally tractable. Traditional multisc…
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…
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…
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…
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…
An Energy Conserving Vlasov Solver That Tolerates Coarse Velocity Space Resolutions: Simulation of MMS Reconnection Events
Florian Allmann-Rahn, Simon Lautenbach, Rainer Grauer
Vlasov solvers that operate on a phase-space grid are highly accurate but also numerically demanding. Coarse velocity space resolutions, which are unproblematic in particle-in-cell…
