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).
