Short Description of Functionality

The program LZKVF computes several characteristic numbers of current data. The data must be given as time-series (in universal direct access data format). The results of LZKVF can be visualised/displayed with the graphical postprocessor HVIEW2D.

The following characteristic numbers can be (optionally) calculated:

Input-Files

general input data (filetype lzkvf.dat)
time series of current data (files of type dirz.bin.r, dirz.bin.i, and dirz.bin)
grid for 2D-data (filetype gitter05.dat/bin or filetype untrim_grid.dat)

Output-Files

results of data analyses for the overall domain (files of type dirz.bin.r, dirz.bin.i, and dirz.bin)
results of data analyses for sectors (files of type dirz.bin.r, dirz.bin.i, and dirz.bin)
informative printer file (filetype lzkvf.sdr)
(optional) trace of program execution (filetype lzkvf.trc)

Methodology

This program is able to generate statistics of current velocity time-series. LZKVF determines the frequency distribution of velocity for different velocity-intervals and sectors of current direction.
The number of intervals and sectors as well as the value of their upper and lower limits can be defined by the user.
Analyses can be carried through for depth averaged current velocity data only.
