Inquiry regarding the current status and location of the Aeroacoustics (FW-H) Solver in SU2

[woranopla]

Does the current version of SU2 include a built-in aeroacoustics/FW-H solver for noise prediction if have where it is? or is an external tool required?

As far as I know, there is no FW-H code coupled with SU2. There was a Python code developed by Eduardo Molina for determining the far-field noise spectra and directivity plots for the Tandem Cylinders test case [1]. The code is an implementation of Farassat’s 1A variant of the integral solution for the FWH acoustic transport equation. We used this code and extended it for the airfoil case[2,3]. If you'd like, I can share it.

Hi Huseyin, Can this also be added to SU2, is a lot of work needed to get this implementation to a general user-friendly state?

Hi, thank you so much for the clarification! That would be extremely helpful for my research on UAV propeller noise. I would be very grateful if you could share the Python code and perhaps a sample configuration or a brief guide on how to interface it with SU2 output. This is exactly what I need for my Master's thesis. Thank you again for your kindness!

Hi Nijso, I am not sure how to add it to SU2, since this is a standalone Python code. I can share the code, and maybe you can check how to add it. We can make it more user-friendly, if needed.

@woranopla: Give me a few days, so I can combine some sample input files and share them.

@ozdemirh has provided me with a package, I have placed it at our SU2 google drive. When we can find somebody with time to work on this further, we can add the code with the validation, etc. to the main SU2 repository.

Please let us know how this works out for you.
