Query: Parallel-in-Time Simulation of an Electrical Machine using MGRIT   We apply the multigrid-reduction-in-time (MGRIT) algorithm to an eddy current
simulation of a two-dimensional induction machine supplied by a
pulse-width-modulation signal. To resolve the fast-switching excitations, small
time steps are needed, such that parallelization in time becomes highly
relevant for reducing the simulation time. The MGRIT algorithm is well suited
for introducing time parallelism in the simulation of electrical machines using
existing application codes, as MGRIT is a non-intrusive approach that
essentially uses the same time integrator as a traditional time-stepping
algorithm. We investigate effects of spatial coarsening on MGRIT convergence
when applied to two numerical models of an induction machine, one with linear
material laws and a full nonlinear model. Parallel results demonstrate
significant speedup in the simulation time compared to sequential time
stepping, even for moderate numbers of processors.
