Class
    Foam::fv::CodedSource

Description
   Constructs on-the-fly fvOption source

    The hook functions take the following arguments:

    codeCorrect
    (
        GeometricField<Type, fvPatchField, volMesh>& field
    )

    codeAddSup
    (
        fvMatrix<Type}>& eqn,
        const label fieldi
    )

    constrain
    (
        fvMatrix<Type}>& eqn,
        const label fieldi
    )

    where :
        field is the field in fieldNames
        eqn is the fvMatrix

Usage
    Example usage in controlDict:
    \verbatim
    energySource
    {
        type            scalarCodedSource;

        active          yes;

        name    sourceTime;

        scalarCodedSourceCoeffs
        {
            selectionMode   all;

            fields          (h);

            codeInclude
            #{

            #};

            codeCorrect
            #{
                Pout<< "**codeCorrect**" << endl;
            #};

            codeAddSup
            #{
                const Time& time = mesh().time();
                const scalarField& V = mesh_.V();
                scalarField& heSource = eqn.source();
                heSource -= 0.1*sqr(time.value())*V;
            #};

            codeSetValue
            #{
                Pout<< "**codeSetValue**" << endl;
            #};
        }

        sourceTimeCoeffs
        {
            $scalarCodedSourceCoeffs;
        }
    }
    \endverbatim
