Defining Acoustic Couplings

You can apply an acoustic coupling to create a tie constraint between the mesh in an acoustic domain and the mesh in the surrounding structural domain.

Support Selection
  1. From the Abstractions section of the action bar, click Acoustic Coupling .
  2. Optional: Enter a descriptive Name.
  3. Specify the Main and Secondary surface supports for the coupling. You can choose an acoustic domain mesh or a structural domain mesh for either surface.
  4. Clear the Adjust secondary check box to prevent the app from moving all tied nodes on the secondary surface onto the main surface.
  5. Specify the Position tolerance, a value that determines the distance within which the app ties nodes on the secondary surface to the main surface. The default tolerance is 10 mm.
  6. From the Main surface options, specify whether you want to use an Element-based or Node-based definition for the surface.
  7. For an element-based main surface, specify the Formulation for the coupling. You can select Node to surface or Surface to surface.
  8. Click OK.
