In general, to build a TUFLOW model in SMS, use the following steps:
1. Start SMS.
|
1. Start SMS, or clear existing projects in SMS.
|
- If SMS is already running, select File | Delete All.
- A new project can also be started by using CTRL + N.
|
|
2. Import data.
|
1. Gather and open image files.
|
Images are imported into the GIS module in SMS.
2. Import images from the web.
|
|
|
|
3. Review and edit elevation data.
|
1. Review elevation data for errors.
|
1. Use the Dataset Info dialog.
|
- Find the "Z", "elevation" or "depth" datasets on the geometric object (mesh, TIN, grid, raster) that is being reviewed
- Right-click on elevation data and select Info.
- Review information in the Dataset Info dialog to see that the range of values are as expected.
|
2. Use contour display options.
|
- Turn off Points and Triangles, then turn on Contours in the Scatter tab of the Display Options dialog.
- Set contour options in the Contours tab. The "Color Fill" option is recommended for this.
- Look for inconsistent points (points with values much higher/lower than their neighbors or regions where no data points exist).
- Verify that the region being modeled is covered by the elevation/depth data and there are no holes.
|
3. Rotate the elevation data.
|
- Use the Rotate tool to examine the elevation data from different angles.
|
|
2. Remove erroneous points and triangles.
|
- After reviewing the imported data, points or triangles covering regions where there are no data points should be deleted. This could include outlier points or thin triangles.
2. Manually remove points.
|
- Use Select Scatter Point tool to select erroneous points in the scatter set.
- Review and edit point data in the Edit Window.
- Delete erroneous points.
|
|
3. Add breaklines.
|
- Select the Create Breakline tool.
- Click along points of a common elevation, such as at a bank toe or levee crest, to connect these points in the surface.
- Use the Backspace key to back up if an erroneous selection is made.
- Double-click or press Enter key to complete the breakline.
|
|
4. Define model limits (domain).
|
- Generate a TUFLOW Grid Extents coverage in the map module.
- Digitize arcs to define grid limits.
- Create arcs along key breaklines and notable features (banklines, structures, piers, road embankments, etc.).
- Assign scatter data.
- Create the grid frame.
- Generate grid.
|
5. Set-up boundary conditions.
|
- Create a TUFLOW 1D/2D BCs and Links coverage.
- Create arcs and polygons.
- Assign boundary conditions to arcs.
|
6. Define general material properties.
|
- TUFLOW requires both general material data properters and TUFLOW specific materials.
- Open the Materials Data dialog.
- Add materials.
|
7. TUFLOW simulation setup.
|
- Create new simulation.
- Add components to simulation.
|
8. Define TUFLOW material sets.
|
- Create new material set.
- Add define material properties.
|
9. Run TUFLOW.
|
- Check model simlation.
- Run TUFLOW.
|
10. Find problems and verify model.
|
|
- Open Check Files that were generated from the TUFLOW run.
- Use GIS module tools to review data.
|
10. Review results.
|
- Open _XMDF file.
- Results layers.
- Observation lines.
- Summary table.
- Run the Plot Wizard.
- Data calculator.
