Hi

Do not use the ACT extension.

 

Use the ANsys native acoustics systems called Harmonic Acoustics.

See here for a tutorial

Also now when you have acoustic domain on one side only of the shell, that is OK - use shared topology so share nodes on the interface between the 2 domains and avoid using contacts between them (see tutorial where share topology is used) .
(As we said we can not have an acoustic domain on both sides of a shell/surface body, but on one side like shown in the image is OK)

All the best

Erik
