涡流问题的时域分析通常需要长时间间隔的模拟，例如直到达到稳定状态。例如在脉冲宽度调制信号中的快速切换激励另外需要非常小的时间步长，这显著增加了计算时间。为了加快模拟速度，可以使用时间并行方法。本文在时间并行方法Parareal的背景下，利用粗传播子的简化模型，研究了显式和隐式时间积分方法的结合。
The time domain analysis of eddy current problems often requires the simulation of long time intervals, e.g. until a steady state is reached. Fast-switching excitations e.g. in pulsed-width modulated signals require in addition very small time step sizes that significantly increase computation time. To speed up the simulation, parallel-in-time methods can be used. In this paper, we investigate the combination of explicit and implicit time integration methods in the context of the parallel-in-time method Parareal and using a simplified model for the coarse propagator.
