Hello guys...I would like to have Su Sp source applied on a part of field under if condition.

- semiImplicitSorce:
here I can define Su and Sp source sadly only for whole field

sourceTerm
{
    type            scalarSemiImplicitSource;
    enabled         true;

    scalarSemiImplicitSourceCoeffs
    {
        selectionMode   all;
        volumeMode      absolute;
        injectionRateSuSp
        {
            k           (1e30 1e30);
        }
    }
}

I don't want to define "cellZone" because it should be mesh independent.

- codedSource:
here I can do a "if" loop over the partial domain, but I don't know how to define Su and Sp

sourceTerm
{
    type            scalarCodedSource;
    name            sourceTerm;

    scalarCodedSourceCoeffs
    {
        selectionMode   all;
        volumeMode      absolute;
        fields          (k);

        codeInclude
        #{
        #};

        codeCorrect
        #{
        #};

        codeAddSup
        #{
            // Cell center coordinates
            const volVectorField& C = mesh_.C();
            const volScalarField& ySwitch = mesh_.thisDb().lookupObject<volScalarField>("ySwitch");
            scalarField& kSource = eqn.source();

                // Apply the source
                forAll (C, i)
                {
                    if (ySwitch[i] > 0.9999)
                    {
                        // cell volume specific source
                        kSource[i] += 1e30;
                    }
                };

        #};

        codeConstrain
        #{
        #};
    }
}

So is there some option please how can I define Su, Sp in codedSource or how can I do a "if" loop inside of semiImplicitSource?
