Hello,
I'm new to OpenFOAM and trying to simulate a flow in a channel to learn OpenFOAM. I'm running multiphase (water and air) case so I would like to assign flowrate where alpha.water is 1 (which is z<=0.8 in my case. I used the following code in my 0/U file but nothing is happening to the model. Can someone who has experience with codedFixedValue chime in on this? I would appreciate the help. Thanks.

Here in the inlet BC from 0/U file

inlet
    {
        type            codedFixedValue;
        value           uniform (0 0 0);
        name            inletBC;
        code            

        #{
                const fvPatch& boundaryPatch = patch();
                const vectorField& Cf = boundaryPatch.Cf();
                vectorField& field = *this;

                forAll (Cf, faceI) // loop over all the patch faces
                {
                    const scalar x = Cf[faceI].x(); // y coordinate of the face
                    const scalar y = Cf[faceI].y(); // y coordinate of the face
                    const scalar z = Cf[faceI].z(); //  y coordinate of the face

                    if (z <= 0.80 && y <= 2 && x <=0.1 )
                    {
                        field[faceI] = vector(1, 0, 0);

                    }

                    else
                    {

                    field[faceI] = vector (0, 0, 0);

                    }

                }
            #};
    }
