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:
- maximum current velocity
- mean current velocity
- mean magnitude of current velocity
- duration of high current velocity
- duration of low current velocity
- frequency distribution of current velocity
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.
