This talk is devoted to the simulation and control of time-dependent eddy
current problems. In order to discretize in time, we apply a multiharmonic
approach. The resulting system of frequency domain equations is discretized
either in terms of a FEM method or in terms of a symmetrically coupled FEM-
BEM method. For the resulting large system of linear equations, we construct
block-diagonal preconditioners, used in a MinRes setting, that are robust with
respect to the space and time discretization parameters and all additionally
involved parameters (i.e. conductivity, reluctivity, regularization parameters).
