Short Description of Functionality

The program TR3DIDA is a postprocessor for the numerical model TRIM-3D. This program serves to convert the results stored in the TRIM-3D result files (water level elevation, current velocity, salinity) into BAW-DHs standard data format (universal direct access data format). Optional results (e.g. wind shear stress and bottom shear stress) could be converted as well. The application of this program is a necessity for the usage of various model-independent postprocessors (for graphics and data analysis).

Input-Files

1. general input data (filetype tr3dida.dat)
2. bathymetry and index-arrays (filetype tr2.topo.bin.ind)
3. equivalent grid (filetype gitter05.dat/bin)
   Notice: This file must be generated by TR2GEOM before using this program.
4. model results (filetype tr3.result)
5. (optional) protection polygons (filetype nodes.save)

Output-Files

1. converted results (files of type dirz.bin.r, dirz.bin.i and dirz.bin)
2. informative printer file (filetype tr3dida.sdr)
3. (optional) trace of program execution (filetype tr3dida.trc)

Methodology

The results of a TRIM-3D simulation are interpolated from the staggered nodes of the computational grid (U-, V- and H-nodes) onto the nodes of the equivalent grid (triangles). The error due to interpolation is mainly influenced by the grid-size as well as the local gradients of the physical quantities. The evolution of the bottom can be optionally calculated as the difference between the original bathymetry and the actual bathymetry.
