论文摘要
涡流问题的时间域分析通常需要模拟长时间的间隔，例如直到达到稳态。快速切换激发，例如在脉冲宽度调制信号中，还需要非常小的时间步长大小，从而显着增加了计算时间。为了加快模拟的速度，可以使用并行时间方法。在本文中，我们研究了在平行时间方法模仿的上下文中显式和隐式时间积分方法的组合，并为粗制传播器使用简化的模型。
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 pulsedwidth 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.
