摘要：
A complex multigrid algorithm for the calculation of time-harmonic three-dimensional eddy currents is presented. The finite-element method with edge elements is used for the discretization of the problems. Different multigrid smoothers are compared for two formulations of the time-harmonic eddy-current problem. It turns out that, using the right combination of smoother and eddy-current formulation, the computation times can be substantially reduced.
