Contact between two Acoustic bodies

Defining contact between two acoustic bodies does not require any special settings. You just need to define the MPC bonded contact between the acoustic domains, which automatically sets the Contact element Degree of Freedom (DOF) to Pressure DOF. However, when the nodes at the contact interface do not match, there might be a discontinuity in the pressure distribution, particularly at high frequencies. Therefore, it's recommended to conduct a verification case to assess this impact.
