NAME

       somnec - Compute Sommerfield-Norton Ground Grids

SYNOPSIS

       somnec

DESCRIPTION

       somnec  is a program to generates grids used by the NEC2 program for the Sommerfeld-Norton
       approximation to  realistic  grounds.   It  allows  interactive  user  input  of  relative
       dielectric  constant,  ground  conductivity,  and frequency in MHz.  The output for use by
       nec2 is written out as binary unformatted file.  The program .B nec2 reads this in, if the
       Sommerfield  Norton  Ground  is  specified  in  the  nec2 input cards by the presence of a
       suitable suitable  Ground Parameters Card i.e. a GN card with IPERF set to 2 (coluns 3-5).
       Hence  the  user  is also prompted for a file name, and the grid arrays are written to the
       file.

OPTIONS

       Due to the age of the program, it expects its input to be in the form of punched cards fed
       into  a  hopper.  It doesn't currently take any options, instead the name of the input and
       output files must be entered once the program has been run.

       It is fully documented as part of the report  Numerical  Electromagnetics  Code  (NEC)  --
       Method  of Moments", available as a printed publication in three parts covering the theory
       of operation, the program code and the users' manual.

BUGS

       This program was keyed in by hand from a printed listing.  Thus it is possible  that  some
       extra  bugs  have been introduced. Unformatted binary files are often a fortran minefield,
       particuarly if transported between systems.
