Adjacent
An Adjacent () selection outputs selections adjacent to specified geometric entities or selections. For example, select all domains adjacent to some boundaries or all boundaries adjacent to some domains.
The adjacent geometric entities can be of any type (domains, boundaries, edges, or points) regardless of the geometric entity level for the input selections. To add this node, right-click the Definitions node and choose Selections > Adjacent.
Input Entities
Based on space dimension, select a Geometric entity levelDomain, Boundary, Edge (3D only), or Point for the selections to add or remove from the Input selections list and to create a selection of adjacent geometric entities. Click the Add button () to open an Add dialog that contains selections of the chosen geometric entity level that appear earlier in the geometry sequence. Select one or several of the selections and click OK; you can use the search bar to filter the list. Use the Move Up (), Move Down (), and Delete () buttons to organize the list.
Output Entities
In the Geometric entity level list, choose the type of output entities: Adjacent domains, Adjacent boundaries, Adjacent edges (3D only), or Adjacent points. If the output entities have a lower dimension than the input entities, there are also options to select exterior and interior entities of the union of the input selections.
By default, only exterior entities are selected. For example, if the input selections are domains selections (see 1 in Figure 6-20), and the output is adjacent boundaries, for Exterior boundaries, select
All (default) to select all exterior boundaries (see 2 in Figure 6-20).
Adjacent to outside to select the outer boundaries bounding the domain selection (see 3 in Figure 6-20).
Adjacent to inside to select the exterior boundaries that are adjacent to a cavity in the domain selection (see 4 in Figure 6-20).
None to not select any exterior boundaries.

The options Adjacent to outside and Adjacent to inside are not supported for virtual geometry, for imported meshes, and for mesh-based geometries.
Select the Interior boundaries checkbox to include the interior boundaries in the selection, as shown in Figure 6-21.
