Roller (Thin Layer)
The Roller node adds constraints on the edges of the Thin Layer node. The displacement is zero in the normal direction, but the thin layer is free to move in the other directions. See Roller.
Face Defining the Local Orientations
When an edge is shared between two or more boundaries, the local directions may not always be unique. It is then possible to use the control Face Defining the Local Orientations to select from which boundary the normal direction should be picked. The default is Use face with lowest number.
