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 probably should put in this functionality, since it would basically be just implementing the code to make a circular contour out of little straight line segments, rather than making users do it themselves via lua. Call me lazy.

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.

Keith.

Regardless of the contour, the B.n integral is evaluated by taking the difference of the value of A at the endpoints of the contour. If I understand what you are trying to do correctly, there's no need for you to actually draw your arc--just evaluate A at the endponts and take the difference to get the total flux crossing your arc.

Dave.
