NAME

       nec2, nec2small - Numerical Electromagnetics Code (Antenna Modelling Program)

SYNOPSIS

       nec2 [INPUT] [OUTPUT]
       nec2small [INPUT] [OUTPUT]

DESCRIPTION

       nec2,  is  a  versatile	numerical  Boundary  Element Method (commonly called Method of Moments) antenna modelling code for the analysis of
       antennas and other metal structures.  It solves the integral equations for the currents induced on the structure  by  sources  or  incident
       fields.	The structure may either be excited by voltage sources on the structure, or by an incident plane wave of either elliptic or linear
       polarisation.  The structure and excitation are described in the INPUT file and the output is written to OUTPUT.

OPTIONS

       Due to the age of the program, it expects input in the form of punched cards fed into a hopper.	It currently does not accept any options.

       If OUTPUT is omitted, output is written to stdout and if INPUT and OUTPUT are omitted then the input is taken from  stdin  and  the  output
       written to stdout.

       The  maximum  size  of  problem which the code can handle must be hard coded at compile time and no dynamic memory allocation is performed.
       Two versions are therefore provided suitable for different sizes of problem, nec2 is compiled for a maximum of 10000 wire segments and 5000
       surface patches, while nec2small is compiled for a maximum of 600 wire segments and 200 surface patches.

SEE ALSO

       somnec(1)

       The  NEC-2 code is fully documented in the report Numerical Electromagnetics Code (NEC) -- Method of Moments" by Burke and Poggio, which is
       available as a printed publication in three parts covering the theory of operation, the program code and the  users'  manual.   An  updated
       form of the users' manual part of this report can be found in /usr/share/doc/nec/NECdoc

BUGS

       nec2  has been superseded by nec4, but this revised code has not been made available to the public, so it is possible that some bugs remain
       in this version.

       Also note that many variant source codes exist based on the original FORTRAN-IV listing in the report.  This one is  believed  to  be  cor-
       rectly working, but may still contain extra errors.

ANNOTATE-OUTPUT(1)					      General Commands Manual						ANNOTATE-OUTPUT(1)

NAME

       annotate-output - annotate program output with time and stream

SYNOPSIS

       annotate-output [options] program [args ...]

DESCRIPTION

       annotate-output will execute the specified program, while prepending every line with the current time and O for stdout and E for stderr.

OPTIONS

       +FORMAT
	      Controls the timestamp format, as per date(1).  Defaults to "%H:%M:%S".

       -h, --help
	      Display a help message and exit successfully.

EXAMPLE

       $ annotate-output make
       21:41:21 I: Started make
       21:41:21 O: gcc -Wall program.c
       21:43:18 E: program.c: Couldn't compile, and took me ages to find out
       21:43:19 E: collect2: ld returned 1 exit status
       21:43:19 E: make: *** [all] Error 1
       21:43:19 I: Finished with exitcode 2

BUGS

       Since  stdout  and  stderr  are	processed  in parallel, it can happen that some lines received on stdout will show up before later-printed
       stderr lines (and vice-versa).

       This is unfortunately very hard to fix with the current annotation strategy.  A fix would involve  switching  to  PTRACE'ing  the  process.
       Giving nice a (much) higher priority over the executed program could however cause this behaviour to show up less frequently.

       The program does not work as well when the output is not linewise.  In particular, when an interactive program asks for input, the question
       might not be shown until after you have answered it.  This will give the impression that the annotated program has hung, while it has not.

SUPPORT

       This program is community-supported (meaning: you'll need to fix it yourself).  Patches are however appreciated, as is any feedback  (posi-
       tive or negative).
