摘要
研制了一个三维全电磁粒子模拟并行程序,用于模拟具有复杂几何结构的高功率微波源器件中的电磁场和电子束相互作用随时间非线性演化过程.本文给出基于"块-网格片"的并行区域分解策略,以及建立在该基础上的并行时间积分算法.采用该并行程序计算一典型微波源器件,在上千台处理机上获得可扩展的并行性能,且模拟结果与国际同类型软件具有可比性.
A three-dimensional fully electromagnetic particle parallel program is developed to simulate non-linear temporal evolution of the interaction of intense relativistic electron beams with electromagnetic in the high power microwave devices with complicated geometry.This paper presents the two level parallel domain decomposition strategy used in the parallel program,namely,block and patch strategy,and the parallel time integration algorithm based on it.A typical device with complex geometry is simulated by the parallel program on thousands of processors, which shows the good scalability and the results are comparable to several famous softwares for the same purpose.
