For Center of rotation, the location of the load is taken as the center of rotation as defined in the parent Rigid Domain node.

For Centroid of selected entities select an Entity level — Boundary, Edge, or Point. The available choices depend on physics interface and geometrical dimension.The center of mass is located at the centroid of the selected entities, which do not need to be related to rigid domain itself. As a special case, you can select a single point, and thus position the mass at that point
|
Once chosen, a default Center of Mass: Boundary, Center of Mass: Edge, or Center of Mass: Point subnode is automatically added.
