Thermal element with perfect insulation and no thermal mass
Simscape / Foundation Library / Thermal / Thermal Elements
The Perfect Insulator block represents a thermal element with perfect insulation and no thermal mass.
You can use this block as an insulation for thermal ports to prevent heat exchange with the environment and to model an adiabatic process. 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 temperature at a node.
To set the priority and initial target values for the block variables prior to simulation, use the Variables tab in the block dialog box (or the Variables section in the block Property Inspector). For more information, see Set Priority and Initial Target for Block Variables.
A — Zero heat flow
Thermal conserving port with zero heat flow.
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.
