Acoustic-Acoustic Boundary
The Acoustic-Acoustic Boundary coupling () is used to couple physics interfaces that have scalar pressure field formulations such as Pressure Acoustics, Frequency Domain, Pressure Acoustic, Boundary Element, and the Thermoviscous Acoustics, SLNS Approximation. Two similar physics interfaces can also be coupled, for example, two Pressure Acoustic, Frequency Domain interfaces.
The functionality is similar to the Acoustic BEM–FEM Boundary coupling in the case where Pressure Acoustics, Frequency Domain is coupled to Pressure Acoustics, Boundary Element.
An interior impedance condition can be added between the two acoustic domains using the Impedance (subfeature).
Settings
See Settings for further details about Label and Name.
The default Name (for the first multiphysics coupling feature in the model) is aab1.
Coupled Interfaces
This section defines the physics involved in the multiphysics coupling. The Acoustics and Acoustics lists include all applicable physics interfaces.
When coupling to the Thermoviscous Acoustics, SLNS Approximation physics, it is assumed that the behavior on the interface is adiabatic and ideal-slip like.
