13. Motion Control

../_images/MotionControlRibbon.png

The Motion Control ribbon menu is used to specify the control of a simulated rigid body.

  • Dynamics: The rigid body will be affected by forces/gravity (default).

  • Static: The rigid body will have zero velocity, will not be affected by any forces and have infinite mass. Suitable for stationary objects such as a ground.

  • Kinematics: The rigid body will an infinite mass and will not be affected by any forces; however it can have a velocity.

The motion control of a rigid body can also be set in the Rigid Body Properties and from the Simulation Structure view.

13.1. Effect of Motion Control on Joint status

The Joint status of a joint might change when you alter the motion control of any of its attached rigid bodies.

A joint requires that it is attached to at least one body with motion control Dynamics or Kinematics in order to be enabled.
