Why is my acoustic model is off?
I would like to use acoustic model in Fluent 2019 R2 to analyse noise source of my unevenly spaced fan which is computed in CFX. I exported the result from CFX as the CGNS format and I can imported the result file into Fluent. However, when I right clicked acoustic model in Fluent, it says the 'The acoustics model is not available with the current model settings. Please refer to the User's Guide for further information.' Is it the problem of the license?
