Rigid Motion Suppression
The Rigid Motion Suppression node adds a minimum number of constraints required to suppress rigid body modes. The constraints are selected so that there will be no reaction forces if the external loads are self-equilibrating. If you need to constrain several objects that are not physically connected, you must add as many Rigid Motion Suppression nodes as there are disconnected objects.
Shell Properties
As the constraints are added automatically to the geometrical selection, it is not possible to select individual layers. The selection in this section only acts as a filter for the boundary selection.

Same as interface selection when the node is added.

All other settings for the Rigid Motion Suppression node are described in the documentation for Rigid Motion Suppression in the Solid Mechanics interface.
