To add a Delete Entities node, right-click a 2D or 3D mesh node and select Delete Entities. Then use the following sections to specify the geometric entities to delete:

Define the geometric entities that you want to delete. You choose the geometric entity level from the Geometric entity level list: Choose Domain, Boundary, Edge, or Point to specify the domains, boundaries, edges, or vertices, respectively, that you want to delete. Use All domains, All boundaries, All edges, or All points to select all entities of the specified dimension.

Select the Delete adjacent lower-dimensional entities check box to also delete the adjacent entities of lower space dimensions.
