This is a UNIX version of NEC2 adapted for use with modern computers. It is based on the original FORTRAN77 source and includes the following features:

• Double precision (added 1985)
• Sommerfeld/Norton ground method
• Fixes taken from Arie Voors (the author of 4nec2)
• Redirection of terminal standard input and output

Before you start, adapt the file NEC2DPAR.INC to your needs. You can choose the maximum number of segments used by the program here. A default is already configured.

The gfortran compiler is needed to build the program. A Makefile is included so that you simply have to run make to compile the source:

    $ make

You might test the program with the included example:

    $ nec2dxs < example1.nec > example1.out

If you have installed Xnecview, you can check the results graphically. Start it from the command line with input and output filenames as arguments:

    $ xnecview example1.nec example1.out
