interFoam cup draining BC

joshmccraney · December 25, 2020, 16:30

Hi All

I am running OF 6.0, interFoam. I have a cup with a hole at the bottom. The cup is partially filled with liquid, which flows out the bottom hole of the cup. The current BCs I have at the hole are:

alpha.water

Code:

    hole
    {
        type            inletOutlet;
        inletValue      uniform 0;
        value           uniform 0;
    }

p_rgh

Code:

    hole
    {
        type            totalPressure;
        rho             rho;
        psi             none;
        gamma           1;
        p0              uniform 0;
        value           uniform 0;
    }

U

Code:

    hole
    {
        type            pressureInletOutletVelocity;
        value           uniform (0 0 0);
    }

Are these BCs appropriate? Thanks so much!

Hi,
I have the similar case working on. Did these BCs work for you? Thanks

give me a few days to return to my workstation and i'll check. but whichever i used, it worked. i'll find it and post.

that being said, i pretty much went from this tutorial: https://wiki.openfoam.com/Multiphase...by_Jozsef_Nagy
