Unsteady VOF analysis
 
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.

thats not a problem z momentum need not to be so less in ur case............
