We can not do that in Ansys Mechanical. So we can not import pressures from Fluent 1st since these (cfd) are total pressures and we need only the acoustic portion of the total pressure, something one can not get. And 2nd even if we had that, we can not import cfd pressures on air acoustic domain in Mechanical - only on structures/solids using the FLUREAD command).

So to sum up we can not do a coupled aeroacoustic simulation between CFD and Mechanical acoustics as you want.


The only way is to do it all in Fluent/Aeroacoustics using the FW-H (does not account for housing and instalation effects) or CAA approach (again it might not be possible due to the computation effort).


Thank you
