Pair Convected Acoustic-Structure Boundary, Time Explicit
The Pair Convected Acoustic-Structure Boundary, Time Explicit multiphysics coupling () is used to couple the Convected Wave Equation, Time Explicit interface with the Elastic Waves, Time Explicit interface, in an assembly geometry where identity pairs have been created.
This pair version of the Convected Acoustic-Structure Boundary, Time Explicit coupling makes it possible to take full advantage of the time explicit formulation. See the Pair Acoustic-Structure Boundary, Time Explicit feature for more details.

Coupled Interfaces
This section defines the physics involved in the multiphysics coupling. The Acoustics and Structure lists include all applicable physics interfaces. The The Convected Wave Equation, Time Explicit Interface and The Elastic Waves, Time Explicit Interface can be selected here.
Pair Selection
Add and select the identity pairs where the pair multiphysics coupling feature is applied.
Create separate Identity boundary Pairs for components of the boundary (where the coupling feature is used) if they meet at a corner or sharp edge. One identity pair for each boundary. By default, identity pairs are created automatically when forming an assembly. Use the automatically created identity boundary pair, duplicate it and then edit them removing boundaries, where necessary.
