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…
The muphyII Code: Multiphysics Plasma Simulation on Large HPC Systems
Florian Allmann-Rahn, Simon Lautenbach, Magnus Deisenhofer +1
Collsionless astrophysical and space plasmas cover regions that typically display a separation of scales that exceeds any code's capabilities. To help address this problem, the mup…
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…
Fluid Simulations of Three-Dimensional Reconnection that Capture the Lower-Hybrid Drift Instability
F. Allmann-Rahn, S. Lautenbach, R. Grauer +1
Fluid models that approximate kinetic effects have received attention recently in the modelling of large scale plasmas such as planetary magnetospheres. In three-dimensional reconn…
Multiphysics simulations of collisionless plasmas
Simon Lautenbach, Rainer Grauer
Collisionless plasmas, mostly present in astrophysical and space environments, often require a kinetic treatment as given by the Vlasov equation. Unfortunately, the six-dimensional…
Enhanced conservation properties of Vlasov codes through coupling with conservative fluid models
T. Trost, S. Lautenbach, R. Grauer
Many phenomena in collisionless plasma physics require a kinetic description. The evolution of the phase space density can be modeled by means of the Vlasov equation, which has to…
