In the Piezoelectric MEMS Speaker tutorial model, a Boundary Load is used to manually couple the Solid Mechanics interface and Pressure Acoustics, Frequency Domain interface. Some examples include using expressions to make material properties or boundary conditions functions of the dependent variables of another physics interface. There is no standard that dictates how it necessarily should or can be implemented, as it will vary depending on what is being modeled. This approach is wide and vast with respect to how it can be implemented for defining multiphysics models. The Pressure Acoustics, Transient interface of the probe tube microphone tutorial model, wherein the dependent variable, p2, is used to manually couple it to the Pipe Acoustics, Transient interface through a Pressure condition (as pictured in the previous screenshot). The Model Builder in COMSOL Multiphysics, with the model tree showing the Pressure Acoustics, Transient condition selected, the Settings window showing the Pressure Acoustics, Transient condition settings, and the Graphics window showing the model geometry. The Pressure condition in the probe tube microphone tutorial model, which is used for manually coupling the 1D (pipe) and 3D (exterior) domains in the model. The Model Builder in COMSOL Multiphysics, with the model tree showing the Pressure condition selected, the Settings window showing the Pressure condition settings, and the Graphics window showing the model geometry.

We refer to this multiphysics modeling approach as the manual with user-defined couplings approach, since it involves manually administering the coupling and interaction between physics interfaces. This is done through user-defined variables, expressions, equations, or functions to couple different physics interfaces.

When there is no alternative predefined option to define the multiphysics couplings in a model, there is functionality in the software that provides you with the flexibility to manually implement custom multiphysics couplings. When to Use the Manual Approach with User-Defined Couplings The approach requires more effort to implement than the manual with predefined couplings approach and completely contrasts the automatic approach, which provides an almost fully automated implementation.

Here, we discuss how to implement the approach with a combination of physics phenomena in your model. We refer to this as the manual approach with user-defined couplings. In COMSOL Multiphysics ®, you can manually administer couplings between physics interfaces for which no coupling features are available.
