Overview
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 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
.sstr. Parameters are stored in filename.parand may be used for future use by including them in ./gpivrc.
