Perfect Insulator

Thermal element with perfect insulation and no thermal mass


Thermal Elements


The Perfect Insulator block models a thermal element with perfect insulation and no thermal mass. Physical network block diagrams do not allow unconnected conserving ports. Use this block as an insulation for thermal ports to prevent heat exchange with the environment and to model an adiabatic process.

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

Dialog Box and Parameters

The Perfect Insulator block has no parameters.

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


The block has one thermal conserving port.

Introduced in R2013a
