Rigid Domain
Add the Rigid Domain node and select one or more boundaries to make them a rigid body. Rigid Domain is a material model, with only one material property: the mass density.
By default, an Initial Values node is added (see Initial Values (Rigid Domain)).
You can add functionality to the rigid domain through the following subnodes:
•
Fixed Constraint (Rigid Domain) to fully constrain the rigid domain.
•
Prescribed Displacement/Rotation to prescribe the displacement of individual degrees of freedom.
•
Applied Force (Rigid Domain) to apply a force in given point.
•
Applied Moment (Rigid Domain) to apply a moment.
•
Mass and Moment of Inertia (Rigid Domain) to add extra mass and moment of inertia in a given point.
•
Spring Foundation (Rigid Domain) to add a translational or rotational spring or damper in a given point.
Layer Selection
In the Rigid Domain node, you cannot access individual layers. Thus the selection in this section only acts as a filter for the boundary selection. All layers through the shell thickness act together as a single rigid body.

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