Class
    Foam::fv::codedSource

Group
    grpFvOptionsSources

Description
    Constructs on-the-fly fvOption source

    The hook functions take the following arguments:

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

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

    codeConstrain
    (
        fvMatrix<Type}>& eqn,
        const label fieldi
    )
    \endverbatim

    where :
        field is the name of the field in the fields list
        eqn is the fvMatrix

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

        scalarCodedSourceCoeffs
        {
            selectionMode   all;

            fields          (h);
            name            sourceTime;

            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;
            #};

            codeContrain
            #{
                Pout<< "**codeConstrain**" << endl;
            #};
        }
    }
    \endverbatim
