I am new to OpenFoam and have tried to extract the viscous term from my own PisoFoam, with :

V= turbulence->divDevReff(U);

and get the following error when compiling

UEqn.H:17:28: error: no match for 'operator=' (operand types are 'Foam::volVectorField {aka Foam::GeometricField<Foam::Vector<double>, Foam::fvPatchField, Foam::volMesh>}' and Foam::tmp<Foam::fvMatrix<Foam::Vector<double> > >')
 V= turbulence->divDevReff(U);

can I instead use a sentence like this perhaps, will that give me the same value as the one I tried?:

V=turbulence->nuEff()*fvc::laplacian(U);
