Point Mass
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.
Coordinate System Selection
With the Coordinate system list, select the coordinate system in which the mass moment of inertia tensor is defined.
Point Mass
Enter a Point mass m.
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.
Frame Acceleration Forces
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.
