The Acoustic–Structure Boundary, Time Explicit multiphysics coupling () is used to couple the Pressure Acoustics, Time Explicit or the Nonlinear Pressure Acoustics, Time Explicit interface with the Elastic Waves, Time Explicit interface. The condition is added on the boundary between the fluid domain and the solid domain for modeling acoustic structure interaction (ASI) or vibroacoustic problems. If possible, the Pair Acoustic–Structure Boundary, Time Explicit condition should be used as it will improve the performance of the time explicit method.

See Settings for further details about Label and Name.

The default Name (for the first multiphysics coupling feature in the model) is asbte1.

This section defines the physics involved in the multiphysics coupling. The Acoustics and Structure lists include all applicable physics interfaces. That is The Pressure Acoustics, Time Explicit Interface and The Nonlinear Pressure Acoustics, Time Explicit Interface, and The Elastic Waves, Time Explicit Interface can be selected here.
