SMS:Define Domain (Feature Objects Menu)

From XMS Wiki - http://wikis.aquaveo.com/xms/

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

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

• Rectangular - If the user selects two points or an arc, the user only sets the Offshore Length. If the user specifies a single point, the user sets both Offshore and Along Shore Lengths.

• Semi-circular - If the user selects two points or an arc, the user does not specify the radius, the radius is the distance between the points. If the user specifies a single point, the user sets the Radius.

• Circular - This option only works if the user selects one point. The user then sets the Radius.
