I am trying to revise the incompressibleTwoPhaseMixture codes for interFoam solver.
I want to put the rho1 (dimensionedScalar) to rho3 (volScalarField), the code is shown in

    rho3_
    (
        IOobject
        (
            "rho3",
            U_.time().timeName(),
            U_.db(),
            IOobject::NO_READ,
            IOobject::NO_WRITE
        ),
        U_.mesh(),
        rho1_
    ),
    alpha1_(U_.db().lookupObject<const volScalarField> (alpha1Name)),
    nu_
    (
        IOobject
        (
            "nu",
            U_.time().timeName(),
            U_.db()
        ),
        U_.mesh(),
        dimensionedScalar("nu", dimensionSet(0, 2, -1, 0, 0), 0),
        calculatedFvPatchScalarField::typeName
    )                                                                                 ------line137 
{
    calcNu();
}

However, errors occur when compiling the codes.

incompressibleTwoPhaseMixture/twoPhaseMixture.C:137: error: member initializer expression list treated as compound expression
incompressibleTwoPhaseMixture/twoPhaseMixture.C:137: error: invalid initialization of reference of type 'const Foam::volScalarField&' from expression of type 'Foam::dimensionedScalar'
make: *** [Make/linuxIA64GccDPOpt/twoPhaseMixture.o] Error 1

When I delete the part of rho3, it is OK?

Any comments? Thanks.
