Abstract

Growing computational capabilities and simulation tools based on high-order methods allow the simulation of complex shaped plasma devices including the entire nonlinear dynamics of the Maxwell-Vlasov system. Such simulations model the particle-field-interactions of a non-neutral plasma without significant simplifications. Thereby, new insights into physics on a level of detail that has never been available before provide new design implications and a better understanding of the overall physics. We present a high-order discontinuous Galerkin method based Particle-In-Cell code for unstructured grids in a parallelization framework allowing for large scale applications on HPC clusters. We simulate the geometrically complex resonant cavity of the 170 GHz gyrotron aimed for plasma resonance heating of the fusion reactor ITER and we demonstrate that a highly efficient parallelization is a crucial requirement to simulate such a complex large-scale device.
