7.9.5 Assigning Reflection Coefficients
Choose Select Feature Vertex tool.
Select vertices on the coastline where changes in the reflection coefficients are
desired.
Go to Feature Objects|Vertics<-> Nodes. This splits the coastline arc. Each
coastline arc can be assigned its own reflection coefficient. (Multiple vertices
can be selected and converted to nodes at the same time by using the Shift key
to multiply select the vertices).
Double click on each coastline arc and specify the desired reflection coefficient for
that segment. (If more than one arc will have the same reflection coefficient, the
arcs can be multiply selected using the Shift key and the attributes assigned
using the Feature Objects|Attributes command.)
7.9.6 Assigning Open Ocean Attributes
Choose Select Feature Arc tool.
Select one or more open boundary arcs.
Select Feature Objects|Attributes command or double click on a single arc and
specify the arcs as Open Ocean type. (Note: if a reflection coefficient is desired
along an ocean boundary to simulate a near coastline type situation, the ocean
boundary can be defined as a coastline. Use the instructions for assigning
coastline reflection coefficients).
7.9.7 Setting the Active Scatter Data Function
Choose Feature Objects|Build Polygons.
Double click on the domain area to select the open ocean area of the domain and
activate the attributes dialog.
Assign it to be an Ocean type.
Select the Density radio button and click on the Options button.
Select the "size" function (created in section 7.9.1) for Element Size and the
"elevation" function for bathymetry.
