SMS contains a numbers commands for modifying feature objects.

General Feature Object Commands

The majority of feature objects commands can be found in the Feature Objects menu.

Define Domain

Selecting the Define Domain command will bring up the Domain Options dialog. This option is found in the Feature Objects menu, in the Map module, when CGWAVE or ADCIRC is the active coverage type. A domain is the region to be filled by a finite element mesh. An ocean arc is created that connects to the coastline arc. There are several options for defining the domain:

  1. Select one or more coastline arcs. The ocean arc starts and ends at the extreme ends of the chain of arcs.
  2. Select two vertices or two nodes. The ocean arc starts and ends at the nodes.
  3. Select a single node or vertex along the coastline arc. Define the radius of the ocean arc and the ocean arc starts and ends where it intersects the coastline arc.
  4. Select a single disjoint point. If the point is inside a closed coastline arc (an island), specify the radius of the ocean arc. The ocean arc is a circle that encloses the island.

After selecting an arc(s) or point(s), the Domain Options dialog appears with the following options:

Example of the Domain Options dialog
  • Rectangular – If selecting two points or an arc, only set the Offshore Length. If specifying a single point, set both Offshore Lengths and Along Shore Lengths.

  • Semi-circular – If selecting two points or an arc, do not specify the radius, the radius is the distance between the points. If specifying a single point, set the Radius.

  • Circular – Sets the Radius. This option only works if one point is selected.

Right-Click Menu

Right-clicking on a feature object will bring up a menu. Many of the commands in this menu are standard commands accessible through other menus. Additional commands include the following:

  • Clear Selection – Undoes the selection of the object that was clicked on.
  • Invert Selection – Selects every object of the same type selected, and undoes the selection of the object that was originally selected.
  • Zoom to Selection – Zooms to a closer view of the object selected.

Optional menu items appear according to the active coverage type.
