If no answer comes from here, I would suggest you register at www.diyaudio.com,
then post in this section: software forum
. You might also try the General section.
It is a board for people who build audio for a hobby. Many are amateurs, like myself, but quite a few are professional electrical engineers and mechanical engineers and you are likely to be bombarded with suggestions. Your question does not necessarily have to apply to audio, and besides I've seen many, many discussions on eddy currents there.
