non-relfective BC for Hydro-acoustics

I'd like to compute hydro-acoustics induced by hydrofoil or cylinder.
STAR-CCM+ has non-reflective boundary condition as "Free Stream" in ideal gas.
However, as you know, STAR-CCM+ doesn't have any non-reflective boundary condition in compressible flow of water.
When I compute hydro-acoustic(compressible flow), I only could use "Velocity-Inlet" and "Pressure-Outlet" which could reflect the acoustic pressure wave.
I use IAPWS equation of state.
Please let me know how to treat for Nonreflecting BC

Unfortunately there are no non-reflective BCs for liquids in STAR-CCM+. You will have to use a source near the boundaries of the domain to damp out the acoustic sources, or just ensure that your boundaries are very far from your object under study.
