Re: [femm] Axi-symmetric arcs for FEMMVIEW

[Keith Gregory <k.gregory@lboro.ac.uk>]

Dave,

Yes I do need to know the path but it's not be totally arbitrary, it's 
always circular and I can specify things like the start and end points, the 
radius and the included angle. I have used the idea of adding an arc to the 
geometry (which is mentioned in the manual incidentally) but it gets very 
complicated when the arc I require cuts several different regions rather 
than being confined to one like that required for a torque calculation. In 
addition the method is really clumsy when I need to use several different 
paths in the same solution.
