Wow!!  I would never have thought that would happen.  Perhaps 
something strange or not obvious is going on.  It might just be 
saturating and heating when running the tube coil shown.  I can't 
imagine how being near your DRSSTCIII would heat it up.

Wow!! ok ;-))  I won't "dream" that it is really better now.  I think 
they sort of abandoned most of them since it is easier to do a full 
rewrite.  But the older versions tend to have free student versions 
:-))))  It is not super bad once you get used to it.

We used solid works but they charge $100 for their "student version" 
=:O  There was and EM thing on the pro version or maybe it was an 
add-on.  Very nice modern easy interface but it was never close to 
free.  The Ansoft thing has probably been more thoroughly proven out though.

Gerry,  As far as I can tell it just does fixed DC currents.

Cheers,
