Use the Point Mass node to model a discrete mass or mass moment of inertia which is concentrated at a point.
The Point Mass Damping subnode can be added to specify a mass-proportional damping.
With the Coordinate system list, select the coordinate system in which the mass moment of inertia tensor is defined.
Enter a value or values for the Mass moment of inertia. For 2D models, enter one value for
Jz. For 3D models, enter a single value for an isotropic moment of inertia tensor, 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.
