The Convected Acoustic–Structure Boundary, Time Explicit multiphysics coupling () is used to couple the Convected Wave Equation, Time Explicit 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 in the presence of a stationary background flow. The condition is applicable for physically correct configurations, specifically where the normal component of the background flow is zero, n · u0 = 0.

If possible, the Pair Convected 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 csbte1.

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.
