Uncoupling a Multiphysics Coupling
Figure 3-17: Uncoupling a predefined multiphysics coupling feature.
For each multiphysics coupling feature, for example the Electromagnetic Heating, 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 Heating reverts to None (Figure 3-17) as there is no interface to couple to.
If a physics interface is deleted and then added to the model again, and in order to re-establish the coupling, you need to choose the physics interface again from the lists. This is applicable to all multiphysics coupling nodes that would normally default to the once present interface.
