摘　　要：针对复杂电磁环境下器件多物理效应机理研究需求,研发了半导体多物理效应并行计算程序JEMS-CDS-Device。介绍了JEMS-CDS-Device的架构设计与实现技术。程序基于非结构网格并行框架JAUMIN实现,采用有限体积法(FVM)离散,使用牛顿法全耦合求解"电-载流子输运-热"问题。程序采用"内核+算法库"形式架构,支持2维和3维非结构网格、千万自由度问题并行求解,支持物理方程、离散算法、材料物理模型等的扩展开发。Aiming at the research requirements of multi-physical effects mechanism of devices in complex electromagnetic environment, a parallel computing program for semiconductor multi-physics effects, JEMS-CDSDevice, is developed. This paper introduces the architecture design and implementation technology of JEMS-CDSDevice. The program is based on the unstructured grid parallel framework -JAUMIN. It uses the finite volume method(FVM) to discretize and uses the Newton method to get fully coupled solution of the " electric-carrier transport-thermal" problem. The program which adopts the "kernel + algorithm library" form architecture, supports2 D/3 D unstructured mesh, and can solve problems of tens of millions of degrees of freedom parallelly. It supports extended development of physical effect equations, discrete algorithms, material physics models, etc.
