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.
SEE ALSO

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.
