To edit a mesh in SMS, use the following steps:
1. Check mesh quality.
|
1. 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.
|
|
2. Post-processed mesh editing.
|
- After the mesh have been created, there are several options for editing the mesh.
1. Delete extra elements.
|
- Select an extra element with the Select Elements tool.
- Use the Delete key to remove the extra element.
|
5. Merge multiple meshes.
|
- Select multiple meshes using the Shift key.
- Right-click on a mesh and select the Merge 2D Meshes command.
- Use the Mesh Merge Options dialog to specify how the meshes should be merged.
|
|
3. If needed, patch or pave elements.
|
1. Define area of mesh where the patch will be applied.
|
- Using the Create Nodestrings tool, create nodestrings enclosing the area to be patched.
- The nodestrings do need to create an enclosed area without any gaps.
- Four nodestrings are used to patch a paved area; three nodestrings are used to pave a patched area.
|
3. Generate mesh with patch elements.
|
- Using the new Mesh Generator coverage in the Project Explorer, do the following:
2. Create polygons in the Mesh Generator coverage.
|
- Polygons are not created automatically when arcs are enclosed. To create polygons:
- Use the Feature Objects | Build Polygons command.
|
3. Specify mesh type for each polygon (pave / patch / none).
|
2. Set the Mesh Type, Bathymetry Type, and Material Type for the polygon.
|
- Mesh types include Patch, Paving, Scalar Paving Density, and Constant Paving Density.
- Bathymetry type describes the elevation/topography source for the mesh nodes. Bathymetry types include a constant elevation value, interpolated elevation values from a scatter set, or interpolated elevation values from an existing mesh.
- Material types can be assigned to a polygon using materials previously created in Materials Data dialog.
|
3. Preview and edit the polygon mesh.
|
- Select the Preview Mesh button.
- Use the preview tools to edit the mesh.
- Set Arc Options to adjust distribution of vertices.
- Use Node Options to change how arcs are treated when using a patch mesh type.
|
|
|
4. Merge meshes.
|
- Select multiple meshes using the Shift key.
- Right-click on a mesh and select the Merge 2D Meshes command.
- Use the Mesh Merge Options dialog to specify how the meshes should be merged.
