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.
