Mesh 1
Proceed and generate the mesh using the Physics-controlled mesh functionality. In general, 5 to 6 second-order elements per wavelength are needed to resolve the waves. For more details see the
Acoustics Module User’s Guide
. In this model we use the default Automatic option, which gives 5 elements per wavelength.
