Hi all,
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 Best Regards Hogeon Kim |

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.

Dear Hogeon Kim,
I am dealing with the same topic: hydroacoustic analysis. I did the tutorials for aeroacoustic in StarCCM+ and everything worked. But when I introduce "WATER" it becomes less clear. Have you solved your issue? Which BC should be used? Thank you. Federica |
