The finite element simulation of conductors moving in a magnetic field at elevated speeds, yields oscillatory solutions. To overcome the effect of the huge convection terms, the partial differential equation is stabilised by adding artificial diffusion. Accurate results are obtained by applying adaptive mesh refinement. A rotational magnetic brake with a solid ferromagnetic rotor is simulated. (C) 2001 Elsevier Science B.V. All rights reserved.
