Good morning,

I am performing Aeroacoustic analysis for a wind turbine blade that is rotating in a semi-cylindrical domain. When I am running the unsteady state CFD simulation (after setting up the point receiver and suitable FWH surfaces) I keep getting a Warning that says:

Warning: No implementation for periodic domain for impermeable boundaries, from not rotating region. See Receiver: Point Receiver;Boundary Name: Blade body

After this, when I try exporting the Thickness noise, Loading noise and Total noise files from the point receiver, I see that the files are empty and no data is being collected.

Could anybody please tell me how I can prevent this warning and ensure that the data is collected when I perform FWH analysis?

Thank you,
Sincerely,
Rohith.
