Acoustics Modeling in Workbench - ANSYS e-Learning

Acoustics analysis is important in the design of many common products and structures including speakers, cars, planes, buildings, sonar, and machinery.  The Acoustics ACT Extension combines the ease-of-use functionality of ANSYS Workbench with the power of the ANSYS-acoustics solver.  It provides all of the tools necessary to set up, solve, and post-process acoustics analyses within the Workbench Mechanical environment.

The Acoustics ACT Extension provides access the acoustics capabilities of the ANSYS solver. Tools include menus and other features to define acoustics properties, apply acoustic boundary conditions and loads, assign acoustic-structure interfaces, and post-process acoustic results.  

CAE Associates’ Senior Engineering Manager Steven Hale demonstrates procedures in Workbench for setting up an acoustic-harmonic analysis of a speaker system to predict sound pressure levels. 

Topics include:

  • Geometry and meshing requirements

  • Assigning acoustic domains

  • Using perfectly-matched layers to assign free boundaries

  • Defining acoustic-structure interfaces

  • Running an acoustic-harmonic analysis

  • Reviewing results to obtain near and far-field sound pressure level
