gpiv_t-avg1

Calculates time-averaged mean and variances of piv data.

Usage

gpiv_t-avg [{-dn | --dir_name dir basename}] [{-df | --first_dir N}] [{-dl | --last_dir N}] [{-fb | --file_basename file basename}] [{-ff | --first_file N}] [{-fl | --last_file N}] [{-fx | --file_prefix}] [{-h | --help}] [{-n | --none}] [{-p | --print}] [-relrms] [{-uv | --print}] [{-v | --version}]

Overview

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.
