SOMNEC(1)
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.
