This paper deals with time-domain surface-impedance boundary conditions in computational magnetodynamics considering both magnetic-vector potential and magnetic-field formulation. Based on the resolution of the 1-D eddy-current problem in a semi-infinite slab, the massive conducting region is accounted for by choosing a number of exponentially decreasing trigonometric basis functions covering the relevant frequency range. Herein the method is elaborated for the magnetic-field formulation. Results for both formulations are compared and validated on a two-dimensional test case. [less ▲]

Power Electronics education at the University of Liège exhibits a particular feature, in that a person from industry is directly involved in the teaching of the introductory Power Electronics course since academic year 2007-2008. Together with him, we teach this subject making use of a project-oriented method. After two years of this experience, it is now of great interest to analyze the main benefits of this method for the students, the teaching team at the University and the company involved in the teaching process. In this paper we present through an example the method that is being used. We mention some interesting technical problems encountered by the students during their project work. We also present the evolution of the method from the first year of application in 2007-2008 to the forthcoming third year in 2009-2010. [less ▲]

In this paper, we report progress towards a 3D finite element model for the magnetization of a high-temperature superconductor (HTS): we suggest a method that takes into account a power law conductivity and demagnetization effects, while neglecting the effects associated with currents that are not perpendicular to the local magnetic induction. We consider samples that are subjected to a uniform magnetic field varying linearly with time. Their magnetization is calculated by means of a weak formulation in the magnetostatic approximation of the Maxwell equations (A–φ formulation). An implicit method is used for the temporal resolution (backward Euler scheme) and is solved with the open source solver GetDP. Fixed point iterations are used to deal with the power law conductivity of HTS. The finite element formulation is validated for an HTS tube with large n value by comparing with results obtained with other well-established methods. We show that carrying out the calculations with a single time-step (as opposed to many small time-steps) produces results with excellent accuracy in a drastically reduced simulation time. The numerical method is extended to the study of the trapped magnetization of cylinders that are drilled with different arrays of columnar holes arranged parallel to the cylinder axis. [less ▲]

A nonlinear time-domain extension of the classical linear frequency-domain thin-shell approach is presented. The interface conditions are expressed in terms of the average magnetic flux density throughout the shell thickness and a number of higher order components. The method is elaborated in the frame of the magnetic vector potential formulation. The nonlinear system of algebraic equations is solved by means of the Newton–Raphson scheme. To validate the new formulation, we consider a magnetic plate placed above a double line carrying a sinusoidal current. Results are compared with those obtained with a fine finite-element model.
