Hi Roy,

EZNEC refuses to operate with Tom's coil (wire overlaps and geometry
issues if I recall from the last failure).


Please contact me by email if you think there's EZNEC isn't doing
something as you think it should. I'll either explain why it's doing
what it does or, if there's a bug, will fix it.

Hi Roy,

The complaint is:
Wire 3 segment length too short. L = .01914 m; recommended min. =
..07495 m.
and so on for 800+ lines.

Attempting to find the Src Data results in:
Wires 3 and 10 contact improperly or are too close.
Wires 3 and 11 parallel and contacting.
Wire 3 end 2 contacts improperly or is too close to wire 12.
and so on...

However, on close examination
Pilot Error
The wire is too thick (I noticed this in modeling Tom's coil at the
Corum calculator and hadn't done the correction yet in EZNEC). The
geometry still complains, but it doesn't inhibit processing.

Thanx anyway.
