Hello, I am trying to simulate the passage of a plane acoustical wave through a gas bubble with a shell that is in a liquid. 
I have created all the geometry, necessary boundary conditions and I am trying to create a plane wave passing through the modeling area. I have encountered the following problems.
1. When I click "solve" I get a message that "You have applied an invalid load for the current analysis".
2. also the boundary conditions I created and the wave source itself has a question mark lit up, as if something is wrong. Although I have filled in all the necessary parameters.

Please help me to understand. Thank you!

Also, link to the project file:

Hi

Ansys empl. can not download any files – perhaps other members of the forum can help more here.

Some feedback from us:

Do not use the ACT acoustic extension.

Use the harmonic acoustics system,

see here for some tutorials.
