Hello everybody,
I have a problem with my unsteady VOF analysis about ship resistance calculation. Especially I have problem with the residual of Z-Momentum. Others are looking good. Urgent help is needed. |

You can describe more on what is the problem that you are facing..
What's wrong with the z-momentum residual? diverge or? Do you have good mesh resolution to capture the free surface? |

Yes, I have a denser mesh structure near free surface. But residual of Z-Momentum is diverging. I tried solving with the second order but it is the same. Thank you for your interest. Looking forward for your reply.
