Re: NEC-LIST: Supernec

Good day Renier,

More than half the time, I run models that use over 500
segments. These generally involve wire-grid surface models
of electrically-small structures.

Hi Doug

Regarding simulating loaded monopoles and dipoles, a
SuperNEC user has
recently used the Genetic Algorithm optimizer in SuperNEC to
optimize load
positions and values of a monopole. A short summarized
version of the work
appears in our latest newsletter with a picture of the
constructed monopole.
If you have not received our newsletter via e-mail you will
find the
newsletter posted on our website in a few days.

The free version is fully capable except for a segment limit
of 300, which
is more than sufficient for simulating most antenna types.

SuperNEC can be used either with Matlab or without. The
advantage (and only
difference) of using SuperNEC with Matlab is that the user
can write scripts
and programs to interface with SuperNEC, making it very
powerful and
flexible. The engine is of course based in C++ and uses the
optimized ATLAS
BLAS libraries.

I hope this clears up a few questions.

Regards
Renier Dreyer
