gpiv_sstrain
GPIV_SSTRAIN(1) General Commands Manual GPIV_SSTRAIN(1)
NAME
gpiv_sstrain - Calculates the shear strain from PIV data.
SYNOPSIS
gpiv_sstrain [-d N] [-h | --help] [--no_g ] [-p | --print] [-g | --g] [-v | --version] [filename] < stdin > stdout
DESCRIPTION
gpiv_sstrain calculates the shear strain from PIV data. You can choose from several differential schemes: central differentiation, least
squares and Richardson extrapolation. The output can be generated as ASCII data containing four columns or as GNUPlot Data format that
allows one to view/print the data as contour plots.
The configuration parameters (containing the POST key) may be overruled by the command line options, as explained below.
Options
-d N Differential type to be used: central difference (N=0), least squares (N=1), Richardson interpolation (N=2), circulation method
(N=3)
-h | --help
On-line help
-p | --print
Print parameters, command line options and eventually used input and output filenames to stdout. The output is identic of file-
name.par, in case filename is used.
-g Show contour plot of the output with gnuplot.
--no_g Suppresses to show contour plot of the output with gnuplot.
-v | --version
Print version information on standard output, then exit successfully.
filename Input PIV data file. Overrides stdin and stdout. The
output will be written to filename.sstr. Parameters are stored in filename.par and may be used for future use by including them in
./gpivrc.
