FIRST SEGMENT MIDPOINT OF WIRE ... INTERSECTS WIRE ...

[kzyapkov]

I have been using xnec2c to play with antenna simulations, but it is very tedious to use it for optimizations, hence my attempts with necpp.

I wasn' able to build a working model though. See this gist

The nec file works fine with xnec2c, but an identical design build with necpp results in

RuntimeError: GEOMETRY DATA ERROR -- FIRST SEGMENT MIDPOINT OF WIRE #4 (TAG ID #10) INTERSECTS WIRE #1 (TAG ID #1)

I am using the python wrapper, but trying to run nec2++ with this .nec file (or many of the examples in the xnec2c code) results in the same geometry error.

There is a commit in a fork

which addresses the issue.
