Mesh Control Vertices
To use isolated vertices, or vertices adjacent to precisely two edges, only for mesh control, in the Geometry toolbar, from the Virtual Operations menu (), select Mesh Control Vertices (). Then enter the properties of the operation using the following sections:
Input
Select the vertices (points) that you want to use for mesh control in the Graphics window. They then appear in the Vertices to include list. If the geometry sequence includes user-defined selections above the Mesh Control Vertices node, choose Manual to select vertices, or choose one of the selection nodes from the list next to Vertices to include.
Click the Active button to toggle between turning ON and OFF active Vertices to include selections.
The operation removes the selected vertices that are isolated or that are adjacent to precisely two edges. However, it does not remove vertices if that would introduce closed or periodic composite edges. The selected vertices are removed from the geometry but become available when you build the mesh. You can, for example, use a mesh control vertex to control the element size inside a domain.
