Dear Henry:

>> Why do you think there is a problem with the oulet pressure BC? Remember we are solving for pd which is p - rho*g*h, i.e. is constant with depth at the outlet.

Excuse me,...

Hi Mattijs, thank you. Now

Hi Mattijs,
thank you.
Now the utility zipUpMesh works correctly. The corrected mesh passes all the tests of the checkMesh.

Thanks,
Michele.

Dear Mattijs,
thanks for the help. I tried to compile the new zipUpMesh, but I experienced problems (the compilation of the old zipUpMesh executable was instead straightforward).
I obtained the...

Thank you, Henry. Yes, indeed

Thank you, Henry.
Yes, indeed the mesh contains refined regions.
So I assume that the non-orthogonality and skewness parameters are non zero due to the refined faces. That's OK.

Indeed, if I...

I tried running the case even with interFoam (with upwind discretisation for the momentum equations), but I experienced the same issues, i.e.
1. during the first part of the simulation the free...

Thanks for your kind replies.

Thanks for your kind replies. I think I imposed correctly the boundary conditions. The numerical scheme used for the momentum equation is upwind (at the first trials I realised that the gamma schemes...

I'm just starting to use the OpenFOAM. I'm interested in VOF methods for ship hydrodynamics simulations. I had previously used other CFD tools when I worked at University.
The first test I'm making...
