The user can define motion, initial conditions, and friction force using Joint page.

•Motion: Defines the motion of revolute joint. For more information, click here.
•Initial Conditions
•Include Initial Conditions: If checked, enables the user-specified initial conditions (position and velocity).
o Position (PV:R): The initial joint angle, specified in Degrees. If the user inputs the parametric value, the unit is Radian. This angle is the initial angular difference between the x-axis of the joint’s action marker and x-axis of the joint’s base marker. The positive direction is defined by the right-hand rule.
o Velocity (R/T): The initial velocity of revolute joint, specified in Radians/Time. The velocity is the angular velocity of the x-axis of the Action Marker relative to x-axis of the Base Marker. The positive direction of the velocity follows the right-hand rule.
•Strict Initial Conditions: Indicates that the initial condition settings should be strictly enforced. See Common UI Joint for more details.
o If a revolute joint is connected to an FFlex body that is included in the pre-analysis and initial conditions are specified for the revolute joint, the initial rotation must be greater than -90 degrees and less than 90 degrees.

•Include Friction: If this option is checked, the user can define the friction type of revolute joint between Sliding and Sliding & Stiction.
•Force Display: Displays the resultant force vector graphically on Working Window. For more information, click here.
