The 2D Mesh Polygon Properties dialog is used to set meshing options for the conceptual model. See Mesh Generation for a discussion of the conceptual modeling approach.
The following polygon attributes can be set:
- Mesh Type – Specify the mesh generation algorithm. The following options are available:
- Bathymetry Type – Specify the bathymetry source for assignment to the mesh. The following options are available:
- Constant – assignes a constant elevation value to all nodes in the mesh
- Scatter Set – interpolates elevation values from the specified scatter set
- Existing Mesh – interpolates elevation values from an existing 2D mesh
- Material – material type to assign to elements created within the polygon
- Arc Options – Used to modify the feature vertices along the arc. The arc must be selected in the polygon preview window. The following options are available:
- Use Original Vertices
- Distribute Vertices – Change the number of vertices along the arc. A bias can be specified rather than distributing the vertices with a constant spacing.
- Node Options – When the mesh type is set to Patch, the node options are used to define the 3 or 4 sides for the patch mesh generation. If a feature point is selected in the polygon preview window, the following options are available:
- Split – The mesh generation algorithm will treat the two arcs meeting at the feature point as separate sides.
- Merge – The mesh generation algorithm will treat the two arcs meeting at the feature point as a single side.
- Degenerate Edge – The mesh generation algorithm will treat the two arcs meeting at the feature point as a "degenerate edge." When using a degenerate edge, the Patching algorithm will require only 3 sides to be defined. This option is only valid for meshes which allow triangular elements. Only one degenerate edge can be specified per feature polygon.
