The Thermal Stress, Membrane (
) interface combines a Membrane interface with a Heat Transfer in Shells interface. The coupling occurs on boundaries, where the temperature from the Heat Transfer interface acts as a thermal load for the Membrane interface, causing thermal expansion.
When a predefined Thermal Stress, Membrane interface is added from the
Structural Mechanics branch (
) of the
Model Wizard or
Add Physics windows,
Membrane and
Heat Transfer in Shells interfaces are added to the Model Builder.
In addition, the Multiphysics node is added which automatically includes the multiphysics coupling feature
Layered Thermal Expansion.
When physics interfaces are added using the predefined couplings, for example Thermal Stress, Membrane, specific settings are included with the physics interfaces and the coupling features.
For example, if single Membrane and Heat Transfer in Shells interfaces are added, an empty Multiphysics node appears in the model tree. You can choose from the available coupling features but the settings in the constituent interfaces are nor modified.
The Layered Thermal Expansion is used to couple the interfaces.
