To remove isolated faces or faces between two domains from the geometry, in the Geometry toolbar, from the Virtual Operations menu (), select Ignore Faces (). Then enter the properties of the operation using the following sections:

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

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

Use the Ignore adjacent vertices and edges check box to specify if the operation also removes the ignorable vertices and edges adjacent to the faces.

Use the Keep input for mesh control check box to specify that the selected faces disappear from the geometry but become available when you build the mesh. You can, for example, use a mesh control face to partition the geometry to make it possible to sweep a hexahedral mesh. See also Mesh Control Faces.
