Hi

 

It can not be applied on a fluid solid interface (FSI), so on  a face where the structure interacts with the acoustic region.

The BLI goes only on outer faces of acoustic regions (not in contact with any structural bodies) – see as an example here: 41.5. Boundary Conditions and Loading (ansys.com) –

 

 

See here if you can not open the above link:

All the best

Erik
