Innovation & Quality

FINE™/Acoustics 8.1 Release Candidate is now available.

This release comes with a documentation included in the software package, available in our customer area on



This new version focuses on the user-friendliness and robustness, in particular for turbomachinery applications.


New wizard to predict tonal and broadband noise for turbomachinery applications

The Turbomachinery wizard allows to automatically set up, run and post-process the aero-acoustic analysis of tonal and broadband noise for turbomachinery configurations (axial, radial or mixed-flow).


 The main advantages for the users are:

  • Minimum user inputs
  • Fast, reliable and detailed acoustics results
  • Reduction of the design cycling cost

The new wizard allows to predict tonal and broadband noise from a FINE™/Turbo or FINE™/Open CFD solution

Extensive validation campaign

Along with the new Turbomachinery Broadband and Tonal Noise Wizard, we have run a series of validation cases on academic and industrial configurations, among which:

  • Tandem cylinder
  • Airfoil with flap
  • NASA Advanced Noise Control Fan
  • Simple axial fan case from Concepts NREC database
  • Centrifugal vacuum cleaner compressor
  • IMAGE research project “aero-engine” axial fan
  • Blower for air conditioning systems
  • INSEAN E779A marine propeller
  • Mufflers


New Python commands

Additional functions have been added to the Python API to extend the scripting and automatization of your workflows.
