| Abstract: | 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. |
