Kinetic scrape off layer simulations with semi-Lagrangian discontinuous Galerkin schemes
Lukas Einkemmer, Alexander Moriggl
In this paper we propose a semi-Lagrangian discontinuous Galerkin solver for the simulation of the scrape off layer for an electron-ion plasma. We use a time adaptive velocity spac…
