Hi all,
Three questions about B.C:

1-What does it mean? (in bouyantPimpleFoam):

    outlet          
    ground
    {
        type            buoyantPressure;
        rho             rhok;
        value           uniform 0;
    }

2- what does it mean? (in pisoFoam):

    outlet          
    {
        type            inletOutlet;
        inletValue      uniform (0 0 0);
        value           uniform (0 0 0);
    }

3- As you know we need to define only one of P and U in boundaries but we must define something in OF for all parameters. so if we define pressure for example as fixed value what should be defined for U?

Thanks in advances,
