摘　　要：介绍了自主研发的强电磁脉冲多物理效应并行计算程序JEMS-CDS-System的情况,该程序采用时域有限元方法,基于JAUMIN并行自适应结构网格支撑框架研制,并行效能高,可扩展性强,且支持动态负载平衡。通过算例测试表明,该程序对于键合线的电-热-应力失效过程的最高温度与范式等效应力计算结果与COMSOL软件计算结果吻合较好;SiP功率放大模块的热-应力耦合天河2高性能计算平台并行计算结果表明,该程序在CPU1024核时,具有38.1%并行效率。This paper presents the study of massively parallel simulation of multi-physics effect with electromagnetic pluses excitation using a high-performance computing scheme based on JAUMIN.Our in-house time-domain finite element parallel program JEMS-CDS-System is employed for simulating the electro-thermo-mechanical responses of bonding wire arrays and their highest temperatures and von Mises stress are captured and validated in comparison with those of the commercial simulator COMSOL.The thermo-mechanical responses of a part of SiP are simulated and parallel efficiency of our parallel program is assessed by the experiment of its strong parallel scalability.Our parallel program can reach a speedup of 6.095 and strong scalability efficiency of 38.1% on 1024 CPU cores.
