The TUFLOW Grid Options dialog (right-click on 2D geometry component in the project explorer and select Options) is used to specify how TUFLOW will handle the grid data. Some of the options deal with what types of data will be specified on the grid cells. This data can alternatively be specified using coverages and this has several advantages including size of the data, speed of execution, and more opportunities for reuse.
The general options include:
- Materials
- Specify cell by cell
- Specify using area property coverage(s)
- Cell Codes
- Specify cell by cell
- Specify using BC coverage(s)
- Miscellaneous
- Allowing dangling z lines – This turns on/off the TUFLOW command to check for dialing z lines (see the TUFLOW manual for description).
- Override Global Time Step – Since the required time step depends heavily on the size of grid cells, it is often convenient for each grid to have a unique time step when using multiple grids in a simulation. These controls allow the user to override the global time step on a grid by grid basis.
- Default SRF
- External Files (Advanced)
- Read External File in TGC file – This can be used to read an external file from the TUFLOW TGC file.
- Read External File in 2D Domain block of TCF file.
The rest of the dialog is used to tell SMS what kind of data to write from the grid in SMS. The optional data types are materials and cell codes. Materials may be specified using an area property coverage and cell codes can be specified from polygons in a TUFLOW BC Coverage. If a grid (instead of a TUFLOW grid extents coverage) is being used in the geometry component, these properties can also be specified cell by cell. If using an area property coverage, a default material is specified for any areas not inside of a polygon.
