NUMECA FINE / Acoustics 8.1

NUMECA FINE / Acoustics 8.1 | 4.9 Gb

NUMECA International is delighted to announce the official release of FINE / Acoustics 8.1. The new version focuses on the user-friendliness and robustness, in particular for turbomachinery applications.

New in FINE / Acoustics 8.1

New wizard to predict tonal and broadband noise for turbomachinery applications
The Turbomachinery wizard implemented in FINE/Acoustics v7.1 has been extended to enable the computation of tonal noise analysis. Both tonal and broadband noise analysis can now be performed through the wizard. Several improvements have also been integrated for the computation of broadband noise compared to the initial implementation. The Turbomachinery wizard offers a fast, reliable and user friendly solution to automatically perform acoustic analysis for turbomachinery applications. Designed for both axial and radial configurations, the wizard requires minimal user inputs and provides detailed information (Radiated Sound Power, Sound Pressure Level at microphones, acoustic field), enabling ultimately to reduce the design cycling cost.

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

FINE / Acoustics is a complete simulation suite for the analysis of a broad range of industrial applications involving Acoustics, Vibro-Acoustics and Aero-Acoustics, from fast pre-design calculations to detailed large-scale analysis.

Have a look at this demo of the FINE/Acoustics wizard in action.

NUMECA International is a leading developer and provider of Grid Generation, Multi-physics CFD software systems for the multiphysics design simulation and optimization of industrial products and processes. A leader in the field of turbomachinery, NUMECA software is used for the simulation of fluids, acoustics, thermal and fluid/mechanical coupled systems in a wide range of applications. NUMECA has a worldwide presence, with branch offices in the USA, Japan, China, Hong Kong, India and Belgium, as well as a worldwide network of distributors.

Multiprocessors calculations

Multiprocessors calculations are allowed on shared and homogeneous distributed platforms. Non-homogeneous configurations are not allowed.

The following limitations additionally apply:
- Multiprocessors calculations are allowed on distributed platforms in local user configurations provided that the same account is used for all machines,
- Domain administrators are not allowed to run multiprocessors calculations.
- MPICH2 library needs Microsoft .net Framework package before installing NUMECA software otherwise execution of mpiexec.exe will lead to a Windows error message.

Hardware requirements

Next to the standard hardware (monitor, keyboard and mouse), some specific recommendations apply in the use of NUMECA software:
- a mouse with scroll wheel is strongly recommended.
- the monitor should support 24-bit color graphics and have a 1280 x 1024 pixel resolution for adequate visualization.
- an Ethernet card should be installed and properly configured.
- NUMECA Software does not support CXFS (Clustered XFS) and IBRIX disk file systems.

Memory and disk space requirements

The Random Access Memory (RAM) required to run NUMECA software depends upon several factors, in particular including the number of grid points inserted in the grid, the physical models selected (turbulence, adaptation,.), the introduction of non-matching boundary conditions and the selected calculation mode (mixed or double precision).

Similarly, a minimum disk space is required on the hard disk to allow the storage of the project files. The size of these files largely depends upon the number of grid points generated.

Graphics requirements

NVidia graphics cards are fully supported, installed together with the latest drivers.

NUMECA software makes use of the advantages of the available Graphics Card. Some trouble may however come up with the default driver OPENGL since it may not be supported by the user host computer and machine display. In order to set the system compatible with a more portable driver, typically MSW driver is used under Windows instead. Note however that the proposed drivers are usually less efficient in terms of graphical speed than the default driver.
