For computational electromagnetics researchers, it demonstrates the feasibility of parallel-in-time methods for eddy current simulations, though the results are preliminary and incremental.
The paper applies Parareal and MGRIT parallel-in-time methods to eddy current problems, achieving significant speedup over sequential time stepping on a 2D coaxial cable model.
We consider the usage of parallel-in-time algorithms of the Parareal and multigrid-reduction-in-time (MGRIT) methodologies for the parallel-in-time solution of the eddy current problem. Via application of these methods to a two-dimensional model problem for a coaxial cable model, we show that a significant speedup can be achieved in comparison to sequential time stepping.
