For each multiphysics coupling feature, for example the Electromagnetic Heat Source, there is a section that defines the physics interface involved in the multiphysics coupling. By default, the applicable physics interface is selected in the lists to establish the coupling.
You can also select None from the lists to uncouple the node from a physics interface. If the physics interface is removed from the
Model Builder, for example if a
Heat Transfer in Solids interface is deleted, then the
Heat transfer list for the
Electromagnetic Heat Source reverts to
None (
FigureĀ 3-15) as there is no interface to couple to.
