Apply frictionless constraints to prevent surfaces from moving or deforming in the normal direction. You can apply frictionless constraints to both flat and cylindrical surfaces in a part.
When applied to flat surfaces, frictionless constraints mimic the behavior of symmetry boundary conditions. However, unlike symmetry constraints, frictionless constraints do not require the setup of a local coordinate system for surfaces that are not aligned with the global coordinate system. As a result, frictionless constraints provide you with a quicker solution for establishing symmetry on angled and flat surfaces - especially for your larger, more complex models.
