NAME
gpiv_vorty - Calculates the differential quantities vorticity, shear strain and normal strain from PIV data.
SYNOPSIS
gpiv_vorty [-d N] [-h | --help] [-p | --print] [-g | --g] [--no_g ] [-v | --version] [filename] < stdin > stdout
DESCRIPTION
gpiv_vorty calculates the differential quantities like vorticity, shear strain and normal strain from PIV data. You can choose from several differential schemes: central differentiation, least squares, Richardson extrapolation and circulation method. Circulation method only allows one to calculate vorticity, but no strain. The output can be generated as ASCII data containing four columns or as GNUPlot Data for- mat 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.vor. Parameters are stored in filename.par and may be used for future use by including them in ./gpivrc.
