FINE™/Acoustics is a fully CFD Integrated environment dedicated to Aero-Vibro-Acoustic simulations. It provides the capabilities to solve a wide range of aeroacoustics and fully coupled vibro-acoustic problems, from simple pre-design calculations to detailed large scale analyses of complex systems.
GUI for all the modeling steps, from the initial pre-processing, to the solvers’ execution, up to the final post-processing and analysis of results
Direct import of the CFD mesh and advanced projection of the CFD results onto the acoustic mesh
Import of structural meshes and results (for vibro-acoustics)
Import of acoustic meshes generated by HEXPRESS™/Hybrid
Acoustic mesh generation from coarsening or shrink-wrapping of the imported CFD and structural meshes
Large set of acoustic boundary conditions and equivalent acoustic sources.
Easy application of boundary conditions and flexible definition of multiple-domains
FlowNoise (DSNG) solver for the prediction of BROADBAND noise produced by “isotropic” turbulence, relying on a cost-effective CFD RANS analysis
Frequency Response solver (coupled FEM/BEM), modeling the sound propagation in presence of non-uniform mean flow
Strong integration within the FINE™/Turbo Non Linear Harmonic (NLH) CFD method, specifically suited to compute TONAL noise
Ffowcs-Williams & Hawkings (FW-H) solver, implementing the acoustic analogy to model noise radiated by fixed/rotating, solid/permeable surfaces
Eigenvalues (FEM) to evaluate natural acoustic modes (cavity modes), coupled vibro-acoustic modes and modal damping with sound absorption material.
A single integrated solver (coupled BEM-FEM).
Parallelization of all stages (coefficient calculations, system solution, and microphones evaluation).
Cluster solver availability: Windows, Linux (MPI Based)
2D plots (e.g. spectra or time histories at virtual microphones and nodes).
Average evaluator to extract sound power, impedance, intensity, etc. on groups of elements
Representation in linear frequencies and 1/3 octave bands
Automatic calculation of Transmission Loss (e.g. in mufflers)
3D view of computed acoustic fields and distributions
Animation of complex fields (fringe plots)
Recursive execution through batch files (ASCII)
Export of solutions (plots, fields) in proprietary and ASCII file formats
