Stop. make: *** No rule to make target '/opt/openfoam7/src/OpenFOAM/lnInclude/Xfer.H', needed by 'Make/linux64GccDPInt32Opt/FileInterface/FileInterface.C.dep'. Stop.

After checking the directory /opt/openfoam7/src/OpenFOAM/lnInclude/, there is no file named Xfer.H, how do you solve this problem in of6?

Hi,

I made some changes in \Make\file and \Make\options, But I am not sure is that works in your case.

file is changed to :

This is the original files in libAcoustics-master/OpenFOAM-4.1/lib/Make
I checked one by one but they are the same with your post, could you please tell me where did you modified?

Sorry, I compiled version 2.3 and version 4 to Openfoam 6, and I forget which one I changed. I have attached them. If they don't work, maybe you can try to check your environment. I couldn't do this on a computer because it didn't have fftw-3.

the Xfer method have been removed by this commit :

https://github.com/OpenFOAM/OpenFOAM...1c806ff2dd24ea


faces.xfer() is now move(faces)

Hello guanjian,

I run the example of cylinder case in version v2112 , in the acousticData folder, there is only time, pressure fluctuation data on the overserved points. There is no Freq, and spl. Could you help me to figure out what is the problem? thanks!

Hi,

This may be a modification of the new version. As you already have time and pressure fluctuations. You can calculate spl or PSD using matlab.

Hi Guanjiang,

I solved it by activating the "writeFfft"in commonSettings file. Either I can calculate spl equation using the p' value. Thank you very much!

W.
