Development of New 3-D Electromagnetic Particle Simulation Code and Its Applications to Space Plasma Simulations

该SGER奖旨在开发一种三维电磁粒子代码，该代码将能够在200 × 200 × 200网格中处理2000万个粒子。为了实现这一雄心勃勃的目标，新的和独特的计算技术将被引入，包括辐射边界局部处理场，局部，滤波和消除泊松方程及其耗时的解。科学上，这笔拨款将用于研究与等离子体云向周围磁化等离子体膨胀有关的基本物理过程。这个问题对于锂和钡的释放、云、星系等离子体喷流以及彗星大气与太阳风的相互作用等空间等离子体应用非常重要。

This SGER award is to develop a three-dimensional electromagnetic particle code which will be capable of processing 20 million particles in a 200 by 200 by 200 grid. In order to achieve this ambitious goal, new and unique computational techniques will be introduced which include radiating boundaries local processing of fields, local, filtering and the elimination of Poissons equation and its time consuming solution. Scientifically, the grant will be used to investigate the fundamental physical processes associated with plasma clouds expanding into an ambient magnetized plasma. This problem is important for the space plasma applications of the release of lithium and barium, clouds, galactic plasma jets, and the interaction of cometary atmospheres with the solar wind.
