Use the Point Mass node to model a discrete mass or mass moment of inertia that is concentrated at a point.
The Point Mass Damping subnode can be added to specify a mass-proportional damping.
With the Coordinate system list, control the coordinate system around the axis of which the principal mass moment of inertias are defined.
Enter a single value for an isotropic Mass moment of inertia J, or select
Diagonal or
Symmetric to enter a full moment of inertia tensor.
Click to select the Exclude contribution check box to switch off the loads that can be caused by the point mass when the frame is accelerated when using a
Gravity or
Rotating Frame feature. The setting will also determine whether the node will contribute when
Computing Mass Properties.
