I just can't set Thermo-Viscous BLI Boundary for the surfaces I want.
The model is as follows, a tube filled with air and a structure inside. I want to place a Thermo-Viscos BLI Boundary condition on the surfaces where the solid interacts with the fluid.

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) –

All the best
