Mistake in documentation? Linear eddy viscosity models
I think there is a mistake in the documentation in this link.
The mistake can be found right after "leading to:". The second term on the right hand side should have a negative sign. It should be like the following:
-\rho \textbf{R}_{dev} = \mu_t \left( \nabla \overline{\textbf{u}} + \nabla (\overline{\textbf{u}})^T \right) {\color{red}-} \mu_t \left( \frac{2}{3} \nabla \cdot \textbf{u} \right) \textbf{I}
