Hi Everyone,

I am doing simulation of two phase flow in Circular Geomerty. With one inlet surface for water and air inlet from other surface section. I am facing divergence issue after 1.5s of simulation.  Is is due to meshing? Though I have mesh with hexa. Also check Mesh quality which detail are in pic. Please give some suggestions on this. Thanks alot.

The two metrics are okay but I would look into cell volume change and skewness too (set mesh check verbosity to 2). I think that we need to check other things, though.

Add details about models used, phase interaction, phases,...

Best regards, Amine
