Infinite Thermal Resistance

Thermal element for setting initial temperature difference between two nodes


Thermal Elements

  • Infinite Thermal Resistance block


The Infinite Thermal Resistance block represents an infinite resistance, with no heat flow through it. Use this block to set the initial temperature difference between two thermal nodes without affecting model equations.

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


The block has two thermal conserving ports.
