Summary0003564: compiled errors while using DimensionedField<Type, GeoMesh>
DescriptionWhen using DimensionedField<tensor, volMesh>, there is compiling error: no matching function for call to ‘T(const Foam::Field<Foam::Tensor<double> >&, const Foam::Field<Foam::Tensor<double> >&)’ Foam::T(result(), *this);
Steps To Reproduce1.write the following code in createFields.H of the icoFoam application.
    volTensorField Ut = fvc::grad(U);
    DimensionedField<tensor, volMesh> Ud = Ut.internalField();
    Info << Ud.T() << endl;
2.compile and the error occurs.
Additional Informationthe Foam::T() global functions in the FieldFunctions.H is declared as:
    template<class Type> void T(Field<Type>& res, const UList<Type>& f);
However, the member function T() of the class dimensionedField<Type, GeoMesh> is defined as:
     template<class Type, class GeoMesh> tmp<DimensionedField<Type, GeoMesh>> DimensionedField<Type, GeoMesh>::T() const
        tmp<DimensionedField<Type, GeoMesh>> result
            DimensionedField<Type, GeoMesh>::New
                name() + ".T()",
    Foam::T(result(), *this);
    return result;
where the operator() of the tmp<T> return a const reference of T rather than a non-const reference which is required by Foam::T() global function.
So, I modify the above code:
    Foam::T(result(), *this);
    Foam::T(result.ref(), *this);
After this modification, the compilation can be done successfully.
TagsNo tags attached.
