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