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.

If you use nec2++, please cite it as follows:

Timothy C.A. Molteno, ''NEC2++: An NEC-2 compatible Numerical Electromagnetics Code'', Electronics Technical Reports No. 2014-3, ISSN 1172-496X, October 2014.

nec2++ is available precompiled as part of most modern linux distributions, including Debian, Ubuntu and Fedora.

sudo aptitude install necpp

!NOTE! nec2++ now requires LAPACK (unless you use the --without-lapack configure option)

See the INSTALL file. But here is the short version

sudo aptitude install libatlas-base-dev
make -f Makefile.git
./configure
make
sudo make install

To build a debugging version use

./configure --with-bounds

Versions of nec2++ since 1.2.3 now compile fine with the MinGW (http://www.mingw.org/) free compiler tools. Just download the source distribution, and follow the unix installation guide (./configure and make).

NEC2++ has been tested with Microsoft Visual Studio 2013. Step-by-step instructions

• Build the project inside the win32 subdirectory with Visual Studio 2103.
