Session

DescriptionRecent advances in cutting-edge physics applications of kinetic theory in magnetized plasmas will be presented. Plasmas are subject to a multitude of collective effects including electromagnetic global modes, instabilities and turbulence, which span several orders of magnitude in space and time scales. Various dynamically reduced approaches, such as gyrokinetics or hybrid fluid-kinetic, have been developed to circumvent some of these difficulties, but even with these reductions the problem remains extremely challenging. Thanks to progresses in numerical methods, algorithmic development, massive parallelization schemes enabling the efficient use of the most powerful HPC platforms, numerical simulations have achieved increasing levels of realism, making scientific application studies nowadays possible that were previously out of reach. This session represents the third and last part of this minisymposium on simulations of plasmas and is dedicated to the ongoing effort in developing innovative numerical methods for carrying out efficient, flexible and robust kinetic simulations. The set of four presentations will in particular focus on recent efforts in developing various alternative Eulerian-based schemes for carrying out gyrokinetic simulations of the edge region of tokamak plasmas. Among others, these talks will address discontinuous Galerkin and high order finite volume discretization, block-structured grids, as well as polynomial basis representations.
