Periodic Condition (Heat Transfer Interface)
Use this node to add periodic temperature conditions to boundary pairs. The Destination Selection subnode is available from the context menu (right-click the parent node) or from the Physics toolbar, Attributes menu.
For information about the Orientation of Source section, 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.
