HinnSo Ansys (solvers) can do acoustics in general (modal, harm., transient), so that is valid for 2019 R2, and for newer and older releases - as we saw though acoustic transient it is just not exposed in Workbench (for any release).nnACT acoustic extension exposes this transient and other acoustic capabilities in WB, but as you saw it is not supported for releases beyond 19.2. So if one wants to use the act extension, one could use it with 19.2 release (or prior to that).nnAlternatively one could also use APDL (2019 R2 for instance or older and newer releases) to do transient acoustics.nnAll the bestnnErikn
