NEC2++ is a C++ rewrite of the Numerical Electromagnetics Code (NEC-2) with many new features like automatic error detection when you specify the structure incorrectly and much faster execution. Nec2++ can analyse radiating as well as scattering properties of structures. The simulation engine in Nec2++ is compiled into a library for easy integration into automatic antenna design systems or GUI tools. Examples are included for using Nec2++ from C/C++, Ruby and Python.
This is a free (GPL) electromagnetic simulation software compatable with NEC-2. It has been rewritten from the ground up.
Nec2++ consists of a library that can be called from C++, C, python and Ruby, and so it can incorporated into other projects like GUI tools and automatic antenna optimization systems.
There is also an executable necpp that can read antenna description files (like the original). Nec2++ is developed on Debian linux, but will work on a variety of other operating systems.
