Class
    Foam::fv::codedSource

Description
    Constructs on-the-fly source

    \heading Source usage

    Example usage:
    \verbatim
    vectorCodedSourceCoeffs
    {
        fieldNames  (U);
        redirectType    ramp;

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

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

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

        // Dummy entry. Make dependent on above to trigger recompilation
        code
        #{
            $codeCorrect
            $codeAddSup
            $codeSetValue
        #};
    }

    // Dummy entry
