Acceleration of PIC and CR algorithms for High Fidelity In-Space Propulsion Modeling (Briefing Charts)
Abstract
We describe enhancements under development for multi-scale methods to be applied to the high-fidelity modeling of spacecraft electric propulsion systems and their environment. Multiple challenges in multi-scale integration, statistical accuracy, and physical modeling are addressed through a variety of innovative numerical methods and mathematical approaches. We emphasize the advances made on a specialized multi-scale time-stepping integrator for finite-Larmor radius particle trajectories, accelerated collisional-radiative non-equilibrium ionization kinetics through Boltzmann equilibrated level groups, and a novel approach to dynamic phase-space reconstruction which can be used to resolve the problems of multi-scale statistics in particle-based kinetic simulations.
