To remove isolated vertices or vertices adjacent to two edges only from the geometry, on the Geometry toolbar, from the Virtual Operations menu (), select Ignore Vertices (). Then enter the properties of the operation using the following sections:

Select the vertices (points) that you want to ignore in the Graphics window. These then appear in the Vertices to ignore list. If the geometry sequence includes user-defined selections above the Ignore Vertices node, choose Manual to select vertices, or choose one of the selection nodes from the list next to Vertices to ignore.

Click the Active button to toggle between turning ON and OFF the Vertices to ignore 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.

Use the Keep input for mesh control check box to specify that the selected vertices disappear 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. See also Mesh Control Vertices.
