Spectral Solver for Multi-Scale Plasma Physics Simulations with Dynamically Adaptive Number of Moments KU Leuven
© The Authors. Published by Elsevier B.V. A spectral method for kinetic plasma simulations based on the expansion of the velocity distribution function in a variable number of Hermite polynomials is presented. The method is based on a set of non-linear equations that is solved to determine the coefficients of the Hermite expansion satisfying the Vlasov and Poisson equations. In this paper, we first show that this technique combines the fluid and ...
