For a 2D or 3D geometry you can add virtual geometry operations after the
Form Union/Assembly node to, for example, remove small details from the geometry and to prepare it for efficient meshing and analysis. The geometry sequence before the
Form Union/Assembly node defines the “real” (original) geometry. The geometry resulting from a virtual operation is referred to as a
virtual geometry.
The following mesh control operations are available from the Geometry>Virtual Operations menu (
) and can be used to include ignored geometric entities for mesh control purposes to, for example, make it possible to use a mapped mesh:
