Re: [femm] Axi-symmetric arcs for FEMMVIEW

Daves,

Great minds? I've been trying to write a lua script to make circular contours using little straight line segments. It looks like it might be possible but it's not that easy. I want it for a different reason though, because I want to find the total flux crossing an arbitrary circular arc where it is not possible to include an arc in the geometry.

Dave,
I was wondering if you could add the arc function
to FEMMVIEW like you have in FEMM so that it makes
it easy to make a circular contour for torque integration
of force. It is a real pain to have to zoom in and
put short straight line segments to enclose a rotor
with a contour to measure torque.

How come you didn't put that function in FEMMVIEW
in the first place? Or did I miss something?
This would speed up torque measurements an order
of magnitude. I could put in two data points for
a 180 degree arc and presto the contour is done.
It would guarantee closure of the contour.
It would also simplfy LUA scripting
for the same sort of scenario.
