This article proposes an efficient parallelized computation of field/circuit coupled systems co-simulated with the waveform-relaxation (WR) technique. The main idea of the introduced approach lies in the application of the parallel-in-time method parareal to the WR framework. Acceleration obtained by the time-parallelization is further increased in the context of micro/macro-parareal. Here, the field system is replaced by a lumped model in the circuit environment for the sequential computations of parareal. The introduced algorithm is tested with a model of a single-phase isolation transformer coupled to a rectifier circuit.

具有并行波形弛豫的场/电路耦合系统的有效仿真

本文提出了一种与波形弛豫 (WR) 技术联合仿真的场/电路耦合系统的高效并行计算。引入方法的主要思想在于将时间并行方法 parareal 应用于 WR 框架。通过时间并行化获得的加速度在微观/宏观并行的背景下进一步增加。在这里，场系统被电路环境中的集总模型取代，用于超现实的顺序计算。引入的算法用耦合到整流器电路的单相隔离变压器模型进行测试。
