Re: NEC-LIST:How to model a person using wire segments?

Hi everyone

Although you could conceivably create a mesh grid it might be better to use
gridding algorithms already available for NEC programs.
One such program, which SuperNEC uses, is called SIG (Structure
Interpolation and Gridding). The cross sectional dimensions of the
structure, or in this case a human, is used as input and SIG automatically
generates the NEC input file.
