The Acoustic-Pipe Acoustic Connection multiphysics coupling () is use used to couple the pipe acoustics interface to the pressure acoustics interface. It applies in quiescent conditions, that is, for zero background mean flow in the pipe acoustic interface. The coupling is between a point (the end of a 1D pipe) in the pipe acoustics interface and a boundary in the pressure acoustics interface.

See Settings for further details about Label and Name.

The default Name (for the first multiphysics coupling feature in the model) is apc1.
