Grid-Free Electromagnetic Plasma Simulations

Abstract

Basic plasma science plays an increasingly significant role in applications of importance to the United States Air Force. Many of these applications require a fully kinetic description in at least part of the domain. The most common approach is to use a fully Lagrangian framework, where the model is reduced to tracking the evolution of test particles in phase space. Of the many varieties, the most accepted approach is Particle-In-Cell. The PI, with his collaborators, is developing an alternative approach, the Boundary Integral Treecode (BIT). BIT is based on fast summation algorithms and boasts arbitrary accuracy. In a range of numerical experiments, the all scale resolution of BIT has proven to provide a substantial improvement over PIC. A major objective in this currant work is to develop a grid-free electromagnetic formulation of BIT.
