The Acoustic Finite Element (FE) Module gives you all the functionality you need to add fully coupled FE acoustic cavity subsystems to your VA One models.

It is ideally suited for creating accurate models of enclosed acoustic cavities at low frequencies and for optimizing the low frequency performance of poroelastic noise control treatments.

Benefits

• Create accurate models of the response of acoustic cavities at lower
  frequencies (when the response of an acoustic cavity is controlled by a small number of dominant acoustic modes)
  
• Quickly and easily find the optimal location and lay-up of poroelastic noise control treatments for maximum absorption at mid and low frequencies
  
• Create fully coupled structural acoustic models (account for full coupling between FE structural subsystems and FE acoustic cavities)

Features

• Inbuilt volume mesher (easily convert between SEA and FE cavities)
  
• Automatic creation of FE area junctions between FE structural subsystems and FE acoustic cavity subsystems using AutoConnect functionality (full support for non-compatible meshes and modal projection)
  
• Inbuilt Acoustic FE solver for calculating acoustic modes and natural
  frequencies of FE acoustic cavities
  
• Easily apply velocity constraints to surface regions of FE cavity subsystems
• Easily apply impedance boundary conditions to cavity faces and area junctions
  
• Create efficient models of layered poroelastic noise control treatments applied to surface regions of an FE acoustic cavity (uses advanced computationally efficient algorithms based on the full Biot equations)
  
• Fully coupled solution (FE acoustic cavity subsystems are fully integrated within the VA One environment and solution)
