本文提出了一种与波形松弛 (WR) 技术联合仿真的场/电路耦合系统的高效并行计算。所引入方法的主要思想在于将并行时间方法 parareal 应用于 WR 框架。通过时间并行化获得的加速度在微观/宏观平行现实的背景下进一步增加。这里，场系统被电路环境中的集总模型取代，用于准实数的顺序计算。所引入的算法通过耦合到整流器电路的单相隔离变压器模型进行了测试。
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.
