Abstract

This paper deals with the analysis of a shielded induction heater by means of a fast multipole accelerated hybrid finite-element boundary-element model. It concerns an experimental setup with passive and active shielding for mitigating the stray field in the surrounding area. Numerical results of the magnetodynamic model are compared with measurements. Further, various aspects of the numerical scheme are discussed and its efficiency is evidenced
