hi,
i tried to solve the tutorial proposed by Hassan Hemida that concern the filling of a bottle ("Free surface tutorial using interFoam and rasInterFoam", Hassan Hemida, 2008). the problem is that in the tutorial proposed by Hemida the chamber of water is always full while in my case i have this situation only as initial condition. the water infact move from chamber to bottle and the chamber remain empty. I follow all the instruction of the tutorials but i think that there is something of wrong in the boundary condition

hello giack,

I face the absolutely same problem. Could You solve it?
I changed the inlet boundary condition of alpha.water from
Quote:
p { margin-bottom: 0.25cm; line-height: 120%; } inlet
{
type fixedValue;
value uniform 1;
}

to
Quote:
p { margin-bottom: 0.25cm; line-height: 120%; } {
type inletOutlet;
inletValue uniform 1;

value uniform 1;
}

The result is, that the solver continues, but too much air flows in.
Thanks for help

hello all,

to get a more physical behavior of the water inflow I tried different BC for the inlet of the tutorial.

I changed the BC for p_rgh field for the inlet to:
Code:
inlet
    {
        type            prghPressure;
        rhoName         rho;
        p               uniform 0;
        value           uniform 0;
    }
this helped to get better results although I think too much water is flowing in compared to the results from the tutorial of Hassan Hemida.

Any suggestions?

Kind regards
