Translational Free End
Translational port terminator with zero force
Simscape / Foundation Library / Mechanical / Translational Elements
The Translational Free End block represents a mechanical translational port that moves freely, without force.
You can use this block to terminate mechanical translational ports on other blocks that you want to leave unconnected. This is not necessary because if you leave a conserving port unconnected, the physical network sets all the Through variables at that port to 0. However, terminator blocks improve diagram readability.
You can also use this block to set the initial translational velocity at a node.
To set the priority and initial target values for the block variables prior to simulation, use the Initial Targets section in the block dialog box or Property Inspector. For more information, see Set Priority and Initial Target for Block Variables.
Nominal values provide a way to specify the expected magnitude of a variable in a model. Using system scaling based on nominal values increases the simulation robustness. Nominal values can come from different sources, one of which is the Nominal Values section in the block dialog box or Property Inspector. For more information, see Modify Nominal Values for a Block Variable.

R2019b: Capping unconnected ports is no longer required
This block is no longer required. Starting in R2019b, the restriction that disallowed unconnected conserving ports in Simscape™ models has been lifted. Now, if you leave a conserving port unconnected, the physical network sets all the Through variables at this port to 0. However, you can still use terminator blocks to improve diagram readability.
There are no plans to remove the terminator blocks. All existing models that use these blocks work the same as in previous releases.
