GPIV_VORTY(1)						      General Commands Manual						     GPIV_VORTY(1)

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. SEE ALSO

GPIV_VHISTO(1)						      General Commands Manual						    GPIV_VHISTO(1)

NAME
gpiv_vhisto - Tests PIV data by printing/displaying an histogram of the vertical particle displacements. SYNOPSIS
gpiv_vhisto [-g] [-h | --help] [-n N] [-p | --print] [-v | --version] [filename] < stdin > stdout DESCRIPTION
Gpiv_vhisto calculates the histogram of the vertical particle displacement distribution between minimum and maximum values. The parameters read from the configuration resources (containing the key VALID) may be overruled by the command line options, as explained below. Options -g Graphical visualization of the histogram with gnuplot. -h | --help On-line help -n N Override number of bins (default 10, hard coded). -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 -f is used. -v | --version Print version information on standard output, then exit successfully. filename Input PIV file. Overrides stdin and stdout. Output will be written to filename.pdf. The parameters will be written or appended to filename.par and may be used for future use by including them in ./gpivrc. SEE ALSO
gpivtools NOTES
stdin and stdout has still to be implemented. [-f filename ] will be added. AUTHOR
Gerber Van der Graaf BUGS
The program seems to work fine with real PIV data. So far, no serious bugs have been found. 8 November 2006 GPIV_VHISTO(1)
