Description

AddSegments is a BoundaryModifier, used as the modifier argument of the OOF.Skeleton.Boundary.Modify command when editing Skeleton boundaries. It adds a set of Segments to the boundary specified in the boundary argument of the Modify command. The boundary must be an edge boundary.

The group parameter specifies which Segments are to be added to the boundary. It must be either the name of a Segment group or the special placeholder object, selection, referring to the currently selected Skeleton Segments.

Edge boundaries must be constructed from a single contiguous non-branching set of Segments, and they must be directed. Boundary conditions use the direction to determine the boundary normal and the direction of applied Fields and Fluxes. The direction parameter specifies the direction of the boundary being created. Adding Segments to an edge boundary does not change the direction of the existing boundary.

It is an error to attempt to add Segments to a closed boundary, or to add Segments anywhere other than at the ends of a open boundary. Adding Segments that are already part of the boundary is allowed, but does not change the boundary. See Figure 6.65 for examples.

Figure 6.65. Adding Segments to a Boundary

The figure on the left shows an existing boundary (in orange) and some selected Segments (in green). The figure on the right is the result of adding the green Segments to the boundary.

None of the groups of selected green Segments can be added to the existing boundary. (a) doesn't form a unique directed sequence, (b) doesn't attach to an end of the existing boundary, and (c) doesn't attach at all.

Adding the set of green selected Segments to the the open boundary on the left converts it to the closed boundary on the right.
