Fine / Acoustics - a software package designed to perform aero-vibro-acoustic simulation. The application provides great opportunity for a wide range and aeroacoustic vibroacoustic related tasks, ranging from simple calculations estimated at step design details and mechanisms finishing large scale detailed analysis of complex systems.


Key features Fine / Acoustics:
Calculation aeroacoustics and acoustics for different types of devices: aircraft engines and engine nacelles, propellers, open rotors counter rotation, compressors, turbines, noise hulls of aircraft and the wing surface, a helicopter rotor, wind installations, ventilation systems and air-conditioning ducts, automobile mufflers and exhaust pipe, propellers etc.
Calculation vibroacoustics for different types of devices: vibrating structure, NVH (Noise-Vibration-Harshness; Noise - Vibration - Hardness) water pumps, marine constructions, sound deadening panels, engine noise, acoustic fatigue, etc.
Adaptive meshes constructed using HEXPRESS / Hybrid. Rooted in NUMECA module training CAD system and parallel meshing generate conformal mesh body on an arbitrary geometry
Direct import CFD mesh and projection CFD results on the acoustic mesh
Importing the structural grids solids and import strength analysis results (for vibro-acoustic problems)
A large set of acoustic boundary conditions and equivalent acoustic sources
Ease of use and flexibility of the boundary conditions set multiple domains
Prediction broadband noise produced by "isotropic" turbulence, based on CFD RANS calculation
FlowNoise (DSNG) is designed for prediction of broadband noise produced by "isotropic" turbulence. Based on CFD RANS calculation
Implementation of different calculation algorithms: finite element method (FEM) and boundary element method (BEM)
Solver frequency response (sharing FEM / BEM end and boundary elements) used for modeling sound propagation in the presence of an inhomogeneous flow
Solver Ffowcs-Williams & Hawkings (FW-H) implements an acoustic analog for modeling the noise emitted by fixed or rotary, or a permeable solid surface
Determination of the eigenvalues ​​(FEM method) to estimate the natural acoustic modes associated vibroacoustic modes and sound absorption material
Full integration with a nonlinear harmonic analysis in NUMECA Fine / Turbo
The full parallelism in each stage (MPI) on different types of operating systems
Complete visualization of calculation results and export the necessary data
Flexible visualization tools and processing results
A graphical representation of spectra or time diagrams in the virtual microphones and knots)
The averaged estimates to obtain values ​​of sound power, impedance, intensity, etc. by groups of elements
