How can I make structural acoustics work ?

      Hello everyone,


      I am actually working on a bottle as a Helmholtz resonator and for this I'm using the harmonic acoustics module. When I define the bottle as a structure and an acoustic region, a question mark appears next to the acoustic region line. Do you know how to fix this ?

      PS : I joined a photo of the situation below.

      A Helmholtz resonator can be created from the fluid domain alone. There is no need to define a bottle as structure. I inserted your image below so that ANSYS staff, who are not permitted to open attachments, can see the image.

      Thanks for your answer I see your point but how can I make this work by keeping the structural option activated ?
