YOu can to this with patch command. First innitialise your domain. Then go to Adapt-Region and define your buble region here. go back to Solve-Initialize-Patch and patch the values for volume fraction and pressure to the bubble region. So far so good, but I doubt that you will be able to see the bubble collapse...If you suceed please tell me how..
