Hi,

As the air volume fraction is 0.333, it is better to go for  Multiphase ---> Eulerian----> Multi-Fluid VOF model.

You can go through the theory guide: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v222/en/flu_th/flu_th_sec_ifm.html

Also check this section of user guide: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v222/en/flu_ug/flu_ug_sec_mphase_using_steps_eulerian.html%23flu_ug_sec_use_ifm

Please go through forum discussion: Simulating bubble formation in water container (ansys.com)

Thank you
