The Background Potential Flow coupling () is a one-way coupling that couples the background flow calculated by a Compressible Potential flow to the Linearized Potential Flow interfaces. The coupling provides the inputs for the Linearized Potential Flow Model.

See Settings for further details about Label and Name.

The default Name (for the first multiphysics coupling feature in the model) is pfc1.

This section defines the physics involved in the multiphysics coupling. The Source and Destinations lists include all applicable physics interfaces. See Acoustic-Structure Boundary for further details.
