Hello everyone
I want to calculate below equation;

epsilonn = U & fvm::laplacian(U);

And I think result must be a volScalarField so I do it like this;

volScalarField  epsilonn = U & fvm::laplacian(U);

but it gives me below error;

UEqn.H:8:29: 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> > >’)
 volScalarField epsilonn = U & fvm::laplacian(U);

Which I do not know why since inner product must be a volScalarField. I will be thankful, if anyone help me with this problem.

use fvc instead of fvm and your problem schould disappear.

Thanks a lot. it worked. and just another question, how can I have access to the value of the nu in momentum equation in pimpleFoam?

Thanks,
Farzad
