please help me!! excuse my anglish it's not very correct i need to know how to define the boundary condtion between vap(bubbel) and liq intrface for observe the phenomen of bubbel collapse,and how to change pressure in liq/vap phases thanck's so much

Hi!

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..

GOOD LUCK MATEUS

Hi,

Did you solve the bubble collapse problem? I have the same problem and I can't see the bubble collapse. can you help me please. I get very low pressures(like 1 Pa) in my results. any idea? what was the tricks you used to solve the problem?
