Turbulent k and omega values for external flows

Hi @jousefm
I have changed my simulation to LES as I am more interested in the instantaneous solutions rather than averaged.

Since wall functions would not be appropriate for my simulation, how do I know that they have not been used? Do certain models use them and others do not?

I would also like to ask about my boundary conditions and whether they are appropriate for trying to model 3D turbulent flow around the cylinder? Should I increase to a greater velocity to show greater turbulence effects?

Thank you
