Re: NEC-LIST: wire-grid modeling

A triangular grid has some advantages in both in matching the surface that is being
modeling and avoids some of the dispersion issues of the current flow, though it may
generate some others. If you know most of the current flows in a single direction, then there
may be an advantage to a retangular grid oriented along that direction. If you have no clue,
a triangular grid may give better answers for a given density. In the long run, the differences
are probably not substantial, unless you can lower the unknown count substantially with one
method over the other for the same effective density. Bill
