openfoam's libAcoustic and fft
 
Dear:
I am major in acoustic with openfoam and i am a new openfoamer, now i am doing soemthing with a airfoil to plot its SPL,but when i run my case,i find the observers in libAcoustic can't do the fft,.
I hope someone who can help me!
Thank you very much ! \

hi nadaer12138,
i have never used libAcoustic for acoustic simulation due its incompatibility with OpenFOAM-v7, but i used fft as You can see in the documentation:
https://cpp.openfoam.org/v7/classFoa...t.html#details
This observation is not pertinent with the title of this forum, but i hope it can help anyway.
Best regards,
Lorenzo
