Short Description of Functionality

The program ENERF calculates with synoptical data from numerical models further characteristical data, e.g. wind induced energy variation by using current velocity and wind shear stress.

Input-Files

1. general input data file (filetype enerf.dat)
2. configuration data file with calculation rules (filetype enerf.cfg.dat)
3. grid for 2D/3D-data (filetype gitter05.dat/bin or filetype untrim_grid.dat)

   or profile-topography for profile-data (filetype profil05.bin)

   or system file for specific locations (filetype location_grid.dat)

4. synoptic data with the necessary physical quantities as input data (filetype dirz.bin.r, dirz.bin.i and dirz.bin)

Output-Files

1. computed data derived from input data (filetype dirz.bin.r, dirz.bin.i and dirz.bin)
2. informative printer file (filetype enerf.sdr)
3. (optional) trace of program execution (filetype enerf.trc)

Methodology

This program is able to generate further derived physical quantities out of synoptical results from numerical models by using calculation rules. Since the formula interpreter of the program analyzes the calculation rules, an extension or change of calculation rules is possible everytime without changing the program code.

It handles two as well as three dimensional data. With a so called attribute, data at the surface (TOP), at the bottom (BOT) or overall (ALL) is taken into account. If only two dimensional input data is given, the attribute has no effect.

You have access to each component of a vector and you calculate with it, so the calculation results (e.g. skalar products, vector products) are flexible to define. Further information to this point is given in the configuration file ( enerf.cfg.dat), where the calculation rules are defined.
