Re: [femm] femm 3.0 beta version available

["Eckart Nipp" <eckart.nipp@xxxxxxxx>]

Hi Dave,

finally I found a little time to try the new version of FEMM. Basically
I liked the changes, especially the added tools for creating the geometry.
Particularly useful is the possibility to define a group and multiple
copy and rotate or translate it (e.g. slots in an electrical machine).
Also the mirror tool is good but a nice feature would be the possibility
to chose weather to keep or remove the original. Then mirroring in place
can be carried out.

So far I haven't discovered any bug but time was rather limited.

However, I wonder if I understood the circuit thing right. Or maybe it's
just that I had a false expectation. What I thing is very useful is the
possibility of coupling two or more domains and defining them as one
circuit, for instance a short circuit winding where the induced current
flows forward in one copper bar and back in another, i.e. on another
location. Typical examples may be shaded pole motors and the cage rotor
of asynchronous motors. Is it possible to obtain the induced currents in
such parts using the circuit feature?

In general I really like FEMM. It cannot (yet) compete with 10000 US$
software packages but it's far better than what I thought was possible
as freeware. Good work! (Only, I would prefer a linux based program, but
that's another thing) :-)
