Hi FOAMERS
I am trying to simulate flow in an-isotropic porous medium. As you might know, I have to define the permeability as a tensor with zero non diagonal elements. The Darcy source term in the momentum equation becomes

+ ((PermInvTen) & (fvc::Sp(Visc,U)))

where PermInvTen is a tensor with diagonal elements of 1/kxx, 1/kyy and 1/ kzz.
When I am using fvc (explicit) it compiles successfully. However, using fvm (implicit) gives the following error
------------------------------------------------------------------
BR1IM003.C:84:40: error: no match for ‘operator&’ in ‘PermTen & Foam::fvm::Sp(const Foam::dimensionedScalar&, Foam::GeometricField<Type, Foam::fvPatchField, Foam::volMesh>&) [with Type = Foam::Vector<double>, Foam::dimensionedScalar = Foam::dimensioned<double>](((Foam::GeometricField<Foam::Vector<double>, Foam::fvPatchField, Foam::volMesh>&)(& U)))’

Does any one know whether OF can handle the dot product of a tensor and implicitly treated vector or not? Is this a bug in foam?
