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

       nec(1)

       It is fully documented as part of the report Numerical Electromagnetics Code (NEC) -- Method of Moments", available as a  printed  publica-
       tion 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.
