Short Description of Functionality
The program TR2VOR serves as a preprocessor for the mathematical models TRIM-2D and TRIM-3D. On the one hand side the program generates a very compact version of the models bathymetry (with the aim to reduce the amount of memory needed to store the depths at all computational points). On the other hand side some additional index arrays are also generated which are required for an optimized program execution on vector and/or parallel computers with shared memory.
Input-Files
- general input data (filetype tr2vor.dat)
- bathymetry (filetype tr2.topo.bin)
Output-Files
- bathymetry and index arrays (filetype tr2.topo.bin.ind)
- (optional) trace of program execution (filetype tr2vor.trc)
Methodology
From a fully two-dimensional matrix (bathymetrical depths) an optimized compact form is generated by this program. The optimized form does contain only one singular grid cell representing dry land (a dry land grid cell will never be flooded by water during the whole simulation). This single cell is a representative for all dry land cells in the modelling domain. To manage this in a good way, some index arrays are generated which allow for a proper identification of the correct geographical location of all cells (dry or wet).
Additionally index arrays are generated with the list of all red and black grid cells as well as lists for neighbourhood relationships (lower, right, top and left neighbour of a computational cell). The existence of these lists is a necessary prerequisite for any optimized vector-parallel program execution on multiprocessor vector machines using shared memory.
