Perfectly insulated stop to fluid flow
Simscape / Foundation Library / Thermal Liquid / Elements
The Cap (TL) block represents a terminus to a thermal liquid branch. The stop is perfectly insulated, preventing heat transfer with its surroundings.
You can use this block to terminate thermal liquid ports on other blocks that you want to cap. 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 pressure and temperature 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 and Initial Conditions for Blocks with Finite Gas Volume.
A — Mass flow rate and energy flow rate are zero
Thermal liquid conserving port where the mass flow rate and energy flow rate are both equal to zero.

Version HistoryIntroduced in R2013b
R2019b: Capping unconnected ports is no longer required
Behavior changed in R2019b
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.
