Short Description of Functionality
The program GEOMFD2 belongs to the preprocessors of the numerical models FIDISOR/FIDIRB. It is used to map bearing data onto a finite difference grid. Bearing data may have been sorted before on a regular grid.
Input-Files
- general input-data (filetype geomfd2.dat)
- selected bearing data (filetype geom.dat)
- bathymetry stored in FIDISOR/FIDIRB format (filetype topo.bin)
- (optional) calendar-matrix with the numbers of the years for which bearing data have been stored in the bathymetry file (identical format with filetype topo.bin)
Output-Files
- modified bathymetry stored in FIDISOR/FIDIRB format (filetype topo.bin)
- (optional) modified calendar-matrix with the numbers of the years for which bearing data have been stored in the bathymetry file (identical format with filetype topo.bin)
- (optional) trace of program execution (filetype geomfd2.trc)
Methodology
The program can be used in different ways to generate bathymetry and or calendar-matrices:
- Generating model bathymetry from bearing data:
:* Read existing model bathymetry.
:* As before, but initialize all grid cells with LAND values (only the outlines are used).
.* Read outlines for the model bathymetry from the general input data file.
- Generating a calendar-matrix:
* Read existing file with calendar-matrix.
* Read initial-value for the year from the general input file.
* Initialize calendar-matrix. Only the actual year, for which bearing data are stored, will be used.
The calendar-matrix, which has identical outlines compared with actual bathymetry, will be generated in parallel with the bathymetry file.
