NAME
gpiv_nstrain - Calculates normal strain from PIV data.SYNOPSIS
gpiv_nstrain [-d N] [-h | --help] [-p | --print] [-g | --g] [--no_g ] [-v | --version] [filename] < stdin > stdout
DESCRIPTION
gpiv_nstrain calculates the normal 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 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 filename.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.nstr. Parameters are stored in filename.par and may be used for future use by including them in ./gpivrc.
