Clay,

NEC-2 is public domain.  NEC-4 is not, it is licensed and not free.  I
believe that all flavors of EZNEC Ver 4.0 EXCEPT EZNEC/4 use the NEC-2
engine.  NEC-2, as a simulator, has some deviations from reality ...
inductor modeling is one of them, conductors connected at small angles,
traps [see inductors] and modeling buried radial fields are others. 
NEC-4 is significantly more complex, more faithful to reality, and not free.

The native UI to NEC-2 is not friendly, it's origin dates to 80-column
punched cards.  EZNEC is a windows UI to it.

73,
