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…
LeXInt: GPU-accelerated Exponential Integrators package
Pranab J Deka, Alexander Moriggl, Lukas Einkemmer
We present an open-source CUDA-based package that consists of a compilation of exponential integrators where the action of the matrix exponential or the functions on a vector…
An accurate and time-parallel rational exponential integrator for hyperbolic and oscillatory PDEs
Marco Caliari, Lukas Einkemmer, Alexander Moriggl +1
Rational exponential integrators (REXI) are a class of numerical methods that are well suited for the time integration of linear partial differential equations with imaginary eigen…
