Initial Values (Gear)
The Initial Values subnode is automatically added to the Spur Gear, Helical Gear, and Bevel Gear nodes.
You can enter initial values for the rigid body displacement, rotation, and velocities, which can serve as an initial condition for a transient simulation or as an initial guess for a nonlinear analysis. The initial values that you specify are interpreted in the selected coordinate system.
Center of Rotation
Select an option from the list — From Parent, Centroid of selected entities, or User defined.
•
For Centroid of selected entities, select an Entity level — Boundary, Edge, or Point.
•
For User defined, in the table, enter the Global coordinates of center of rotation Xc.
Once chosen, a default Center of Rotation: Boundary, Center of Rotation: Edge, or Center of Rotation: Point subnode is added.
Initial Values: Translational
•
Displacement at center of rotation u.
•
Velocity at center of rotation ∂u/∂t.
Initial Values: Rotational
•
Axis of rotation Ω
•
Angle of rotation
•
Angular velocity ω
