DESCRIPTION¶
gpiv_t-avg calculates mean and variances from a
series of piv data
resulting into time-averaged values. If no parameters are defined at the
command line, standard parameters will be used that are defined in the script.
This program does not use the parameter resources from libgpiv.
Options¶
- -dn | --dir_name dir base-name
- The dir base-name represents the directory name without its last
number. It is supposed that the last number in the directory name is a
counter.
- -df | --first_dir
- Defines the counter N of the first directory number at which the
analyses starts.
- -dl | --last_dir
- Last directory number N at which the analyses ends.
- -fb | --file_base_name file base-name
- The filename has to be given without its .piv extension. The
file base-name represents the file name without its last number,
before the extension. If not -fx key is used, it is supposed that
the last number in the file name is a counter. The output will be written
to dir base-name/file base-name.ta_mean.piv and
dirname/filename .ta_sdev.piv at which mean values and
variances are written respectively or to
dirname/filename.ta_U.piv and to
dirname/filename.ta_V.piv if -uv is used.
- -ff | --first_file
- Defines the counter Nof first file number at which the analyses
starts.
- -fl | --last_file
- Last file number N at which the analyses ends.
- -fx | --file_prefix
- Prefix numbering to file base name.
- -h | --help
- On-line help.
- -n | --none
- Suppresses real execution.
- -p | --print
- Prints parameters, command line options and input and output filenames to
stdout.
- -relrms
- Prints relative rms, related to the absolute mean value.
- -uv
- Writes U and v displacements/velocities to separate outputs.
- -v | --version
- Prints version information to standard output, then exits
successfully.
