Hi Everybody,
I am trying to simulate a three-fluid model (water, air and oil above). First I tried the case only with water and air and I had good results. However, when I inserted the oil above the water it was not phisically valid, with the volume of oil continuously increasing even using degassing condition. Can someone please help on this? Thanks in advance, Filipe. |

Please post an image of what you are modelling and the CCL.

The files are attached!
The two-phase image is physically correct, but the three-phase not (0s, 2s and 6s are represented). Thanks for the patience! three-phase 0s oil VOF.jpg two-phase.jpg three-phase 2s oil VOF.jpg three-phase 6s oil VOF.jpg panela.txt |

Are you sure you are adequately converged?

I think so.. Do you think it could be a convergence problem?
