<p>The Numerical Electromagnetics Code (NEC-2) is a comprehensive package for the analysis of the electromagnetic properties of structures. It can analyse radiating properties i.e. antenna gain, as well as scattering properties (radar cross section) of structures. NEC-2 was originally written in FORTRAN.</p>
<p>NEC2++ is an extensive rewrite of NEC-2 in C++ by Tim Molteno. This work was helped tremendously by the work of N. Kyriazis who ported NEC-2 to C. The new portions of code are licensed under the GNU Public License (GPL).</p>
<h2>Latest version is $nec_version [$nec_date]</h2>
<h2>Check out the <a href='http://www.physics.otago.ac.nz/nec_forum/'>NEC Forum</a> for release notes and more</h2>
<ul>
<li>Download Linux executable for <a href='nec2++.tar.gz'>the latest version</a> $nec_date [500 kB tar.bz2]</li>
<li>Download source code for <a href='necpp_latest.tar.bz2'>the latest version</a> $nec_date [116 kB tar.bz2]</li>
<li>Download a <a href='nec2++.zip'>Windows executable</a> [312 kB zip], created with MinGW</li>
<li>Download a <a href='necpp_$nec_date_short.zip'>Windows Code Distribution</a> [260 kB zip], including a Visual Studio Project file.</li>
<li>A very basic attempt at a users guide will be available soon.</li>
</ul>
<h3>Usage</h3>
<p>To use nec2++, after installation</p>
<pre>
usage: nec2++ [-i input-file-name] [-o output-file-name]
-g: print maximum gain to stdout.
-b: Perform NEC++ Benchmark.
-s: print results to standard output.
-c: print results in comma-separated-value (CSV) format,
this options is used in conjunction with (-s) above.
-h: print this usage information and exit.
-v: print nec2++ version number and exit.
</pre>
<p>The output file name is optional. If it is not specified, a file will be created in the same directory as the input file
and with an extension .out.</p>
<h3>Compilation on Linux/Unix</h3>
<p>Decompress the source-code archive, and issue the following commands. This should work on systems with a C++ compiler (almost all systems)</p>
<pre>
tar -jxf necpp_latest.tar.bz2
cd necpp_$nec_date_short
make -f makefile.dist
make -f makefile.dist install
</pre>
<h3>Compilation on Windows</h3>
<p>Decompress the <a href='necpp_$nec_date_short.zip'>Windows Code Distribution</a>, and build the Visual Studio project inside the win32 subdirectory</p>
<h3>Links</h3>
<ul>
<li>The <a href='http://www.si-list.org/swindex2.html'>NEC Archives</a>.</li>

<h3>Building using Autoconf</h3>
<p>To build libnecpp, and use NEC from a C API, you need to use autoconf and friends -- to install these on <a href='http://www.debian.org'>Debian</a> linux, simply type</p>
<pre>
apt-get install automake libtool
</pre>
<p>To build the library, download the <a href='necpp-1.1.1.tar.gz'>autoconf distribution [1 MB]</a> and issue the following commands:</p>
<pre>
tar -zxf necpp-$nec_version.tar.gz
cd necpp-$nec_version
./configure
make
make install
</pre>

<h3>Release Notes are available from the <a href='http://www.physics.otago.ac.nz/nec_forum/'>NEC Forum</a></h3>
<h3>Notes</h3>
<p>In the very near future, nec2++ will depend on the ATLAS. To install this use the following commands
under DEBIAN linux (http://www.debian.org).</p>
<pre>
apt-get install atlas3-base atlas3-headers atlas3-base-dev
apt-get install refblas3-dev lapack3-dev lapack3-doc
</pre>
<p>For installation on other operating systems, you should look at <a href='http://math-atlas.sourceforge.net'>the ATLAS page</a>.</p>
