To use isolated edges, or edges adjacent to precisely two domains (in 2D) or two faces (in 3D), only for mesh control, in the Geometry toolbar, from the Virtual Operations menu (), select Mesh Control Edges (). Then enter the properties of the operation using the following sections:

Select the edges that you want to use for mesh control in the Graphics window. They then appear in the Edges to include list. If the geometry sequence includes user-defined selections above the Mesh Control Edges node, choose Manual to select edges, or choose one of the selection nodes from the list next to Edges to include.

Click the Active button to toggle between turning ON and OFF the Edges to include selections.

Use the Include adjacent vertices check box to specify if the operation also include the ignorable start and end vertices of the edge.

The operation removes the selected edges that are isolated or that are adjacent to precisely two faces (in 3D) or two domains (in 2D). The edges are removed from the geometry but become available when you build the mesh. You can, for example, use a mesh control edge to control the element size inside a domain or to partition the geometry to make use of a mapped mesh.
