Model-Order Reduction for the Finite-Element Boundary-Element Simulation of Eddy-Current Problems Including Rigid Body Motion

A coupled finite-element boundary-element method for solving parametric models of eddy-current problems is proposed. Affine approximation by the empirical interpolation method makes the numerical model accessible to projection-based parametric model-order reduction. The resulting low-dimensional system provides high evaluation speed at an accuracy comparable with that of the underlying discretization method.
