YARDSTICK(1fe)              Finite Element Package              YARDSTICK(1fe)



NAME
       yardstick - unit conversion and problem scaling application

SYNOPSIS
       yardstick [-il length unit] [-if force unit] [-ol length unit] [-of
       force unit] [-ls length scale factor] [-fs force scale factor]
       [filename]

DESCRIPTION
       yardstick is a program to scale the numerical quantities in a FElt
       input file; converting FElt files from one set of units to another
       (e.g., Newtons and meters to pounds and inches) is a special case of
       this operation and as such is given special treatment.  For unit
       conversion you must specify input and output unit names for force and
       length quantities; yardstick will figure out the appropriate scale
       factors. Mass units are converted based on the length and force units
       that you specify.  Time units are always assumed to be seconds so no
       conversion options are provided.  For simple scaling you simply specify
       multiplicative scale factors for both force quantities and length
       quantities.  Mass and time quantities are treated as in the special
       case of unit conversion.

OPTIONS
       yardstick accepts the following options.  Note that for unit conversion
       all four of -il, -if, -ol, -of must be specified and that unit
       conversion and simple scaling (-fs and -ls) are exclusive options.

       -help
            Write a message describing valid command line options to standard
            error and exit.

       -il (--input-length) length units
            The symbolic name of the length units used in the input file.
            Valid names are m (meters), mm (millimeters), cm (centimeters), ft
            (feet), in (inches).

       -if (--input-force) force units
            The symbolic name of the force units used in the input file.
            Valid names are N (Newtons), MN (mega-Newtons), GN (giga-Newtons),
            lbs (pounds), kips (kilopounds).

       -ol (--output-length) length units
            The symbolic name of the length units for the output (i.e., what
            the input units will be converted to).  Available types are the
            same as for input length units.

       -of (--output-force) force units
            The symbolic name of the force units for the output (i.e., what
            the input units will be converted to).  Available types are the
            same as for input length units.

       -ls (--length-scale) length quantity scale factor
            The multiplicative factor by which length quantities within the
            input file will be scaled.

       -fs (--force-scale) force quantity scale factor
            The multiplicative factor by which force quantities within the
            input file will be scaled.

       -nocpp
            Do not use a preprocessor on the input file.

       -cpp filename
            Use filename as a preprocessor on the input file.  The default
            preprocessor is "/lib/cpp".  Any preprocssor which understands the
            -D, -U, and -I options can be used as these options are passed to
            the preprocessor.
