Using simpleFoam the solver says the momentum equation is:


\div (\vec{U} \vec{U}) - div \gvec{R} = -\grad p + \vec{S}_U




My Question: How does the solver "use" the nu (kinematic viscosity)
i write in the transportProperties?
Usually the nu (kinematic viscosity) should be in the momentum equation as:

nu \laplace c (= diffusion term), right?

Isnt there andy deffusion term in the equation?
