Periodic Condition (Heat Transfer Interface)
Use this node to add periodic temperature conditions to boundary pairs. The Destination Selection section is available if you select the Advanced Physics Options in the Show More Options dialog box.
For information about the Orientation of Source and Orientation of Destination sections, see Orientation of Source and Destination in the COMSOL Multiphysics Reference Manual.
Periodic Condition
Enter a Temperature offset ΔT to the temperature periodicity. The default value is 0 K, so that the source and destination temperatures are equal.
Constraint Settings
To display this section, click the Show More Options button () and select Advanced Physics Options in the Show More Options dialog box.
