Rotational Free End

Rotational port terminator with zero torque


Mechanical Rotational Elements


The Rotational Free End block represents a mechanical rotational port that rotates freely, without torque. Physical network block diagrams do not allow unconnected conserving ports. Use this block to terminate mechanical rotational ports on other blocks that you want to leave unconnected.

You can also use this block to set the initial rotational velocity at a node.

The Variables tab lets you set the priority and initial target value for the Rotational velocity variable prior to simulation. For more information, see Set Priority and Initial Target for Block Variables.


The block has one mechanical rotational conserving port.

Introduced in R2012b
