ASTRA: Efficient Plasma Simulation Software

Author: Bocong Zheng

ASTRA is an efficient plasma particle simulation software. ASTRA combines multiple efficient algorithms to eliminate the spatial and temporal constraints in the state of the art particle in cell schemes. The computation is one to two orders of magnitude more efficient than the current commercial software.
