Re: [FEMM] bc mistake??

I responded before I looked at your file.  

Your segments don't match.  

You have no matching edge for ap3 that I could find.  

The aluminum cuts the segment line in half and the line
segments can't be the same.

Also, check the polarities of your current in the windings.
