Abstract

We present a systematic study of how to take into account external excitation in the eddy current model. Emphasis is put on mathematically sound variational formulations and on lumped parameter excitation through prescribed currents and voltages. We distinguish between local excitation at known contacts, known generator current distributions and non‐local variants that rely on topological concepts. The latter case entails the violation of Faraday's law at so‐called cuts and prevents us from reconstructing a meaningful electric field. Copyright Β© 2004 John Wiley & Sons, Ltd.

This paper deals with the upscaling of the time-harmonic Maxwell equations for heterogeneous media. We analyze the eddy-current approximation of Maxwell's equations to describe the electric field for heterogeneous, isotropic magnetic materials. The magnetic permeability of the materials is assumed t

The Antarctic Circumpolar Current (ACC) is an important and integral part of the global ocean conveyor belt that connects the major ocean basins. Coarse resolution global climate models therefore need a realistic simulation of the ACC in order to correctly transport anomalies of heat and freshwater
