Short Description of Functionality
The program TR2LQ2 is a preprocessor for the mathematical models TRIM-2D and TRIM-3D. It was designed to extract bathymetry-data along longitudinal or cross-sectional profiles from a TRIM bathymetry and index arrays containing file. Every profile is defined by a sequence of an arbitrary number of 2D-locations which are connected by straight lines. Additional points can be easily inserted automatically at regular intervals in between these 2D-locations.
Input-Files
- general input data (filetype tr2lq2.dat)
- (optional) old profile-topography (filetype profil05.bin)
- (optional) profiles (filetype prof.bin)
- several other files are necessary to define the 2D-Locations and profiles where data shall be extracted (see documentation for the file tr2lq2.dat)
- bathymetry and index arrays (filetype tr2.topo.bin.ind)
Output-Files
- profile-topography (filetype profil05.bin)
- decriptions of all geo positions divided into profiles (filetype gprofil.dat)
- depth values of all points divided into profiles (filetype tprofil.dat)
- informative printer file (filetype tr2lq2.sdr)
- (optional) trace of program execution (filetype tr2lq2.trc)
Methodology
A comprehensive profile-topography is generated from the various input-data. 2D-locations are gathered to form profiles. Additional new points can be automatically inserted in between these locations at arbitrary intervals. Bathymetric depth is calculated as the maximum of the depth values given at the four computational nodes (U- and V- points) defining a cell in the computational grid. Text-strings can be related to locations and profiles. A list of node numbers as well as connexion-tables are generated for all segments. Optional information is also generated for data-interpolation (used by subsequent post-processors). New bathymetry data can overwritten to an already existing profile-topography.
