This example problem demonstrates the use of acoustic elements coupled with structural elements to examine the performance of a speaker assembly.
The following features and capabilities are highlighted:
Structural-acoustic coupling using fluid-structure interaction (FSI) in 3D
Use of a symmetric FSI algorithm
Use of perfectly matched layers (PML) to absorb outgoing acoustic waves
Postprocessing sound pressure level (SPL) and velocity
Far-field postprocessing of acoustic field
User-defined symmetric expansion options
