Dear all,

I am building a new solver using the version 2.3.x of OF, and I have an issue with compiling this solver rising from the energy equation. The equation looks like:
fvScalarMatrix EEqn
(
fvm::ddt(rho, hi) + fvc::ddt(rho, e)
+ fvm::div(rho*U, hi) + fvc::div(rho*U, e)
+ fvm::div(p, U) - fvm::laplacian(kEff, T)
);

hi being the internal energy of the fluid and e the specific energy, kEff the effective conductivity and U and rho obviously the velocity and fluid density.
However the solver returns the following error:
error: no matching function for call to ‘div(Foam::tmp<Foam::GeometricField<Foam::Vector<d ouble>, Foam::fvPatchField, Foam::volMesh> >, Foam::volScalarField&)’
+ fvm::div(rho*U, hi) + fvc::div(rho*U, e)

Same error which logically comes back for every 'div' statement in the equation. I understand from the log that openfoam complains about me trying to compute the divergence of a geometric field double and a volscalarfield as arguments, but then how can I compute this equation ??

Thanks a lot for your help !!
