Template:SRH Generate Mesh Workflow

1. Set vertex spacing on arcs to define mesh element size.
Using the Select Feature Arc tool, select arc(s) and use the Redistribute right-click command. Use the Redistribute Vertices dialog to set the vertex distribution.

2. Stamp new features (channel, roadway embankment, or other).

3. 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.

4. Specify mesh type for each polygon (pave / patch / none).

1. Select a polygon and open the 2D Mesh Polygon Properties dialog. Use the Select Poylgon tool to select a polygon. Double-click on the selected polygon or use the Feature Objects | Attributes menu command. 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.

5. Generate mesh from the Mesh Generator coverage.
Select the Mesh Generator coverage and use the Map → 2D Mesh right-click command. Review the mesh quality for the newly generated mesh.
