Documentation
VNoise is a complete suite for acoustic analysis. The basic module include a state of the art Boundary Element Solver for the analysis of acoustic and vibro-acoustics problems. Typical fields of applications include NVH, design of absorbing barriers, analysis of inlet and exhaust systems and many others. Additional modules are available for aeroacoustics analisys, rotor and duct acustics.
 
The advanced computational features are complemented by a powerfull and friendly user interface for pre and post processing. Specific interface modules are available for integrating VNoise with commercial FEM and Meshing packages. A parallel distributed solver is also available for distributing large scale calculations on a standard PC network.
VNoise has a number of advanced and user friendly capabilities, and is specifically designed in order to make "life easy" for users, keeping at the same time the required power and flexibility:
  • Interfaces with NASTRAN, ANSYS, FEMAP, NEi Nastran, Patran.
  • Advanced Mesh Coarsening and Interpolation.
  • Complex speed of sound and density.
  • Thin shells, mixed domain, and multi domain formulations.
  • Modelling of Perforated surfaces.
  • Plane, axial symmetries, and Half space formulations.
  • Evaluation of SoundPower, Intensity, Transmission Loss.
  • Aeroacoustic sources.
  • Parallel/Distributed Solver.
  • Batch Files

Top Performances: Compare the analysis times on the right (obtained with a Quad-core PC) with VNoise competitors and you will be surprised by how VNoise scales well when increasing the number of nodes
