This example demonstrates:

The animation of spring and damper components
A body can be freely moving without any connection to a joint. In this case body coordinates are used automatically as states (whenever joints are present, it is first tried to use the generalized coordinates of the joints as states).
If a body is freely moving, the initial position and velocity of the body can be defined with the "Initialization" menu as shown with the body "body1" in the left part (click on "Initialization").

animation	Value: true Type: Boolean Description: = true, if animation shall be enabled
