Hello @jousefm, thank you for your response.
I chose RANS simulation because I was lead to believe that LES would make resolving near wall regions difficult. Why would LES be a better choice? When you say ‘not use the whole length of the cylinder’, do you mean make the cylinder a shorter length and increase the meshing dimension in that direction?
Why do you suggest that I increase my domain further rather than use the standard 2-3D upstream and 6-8D downstream recommendation?
Another question is that I am confused how to calculate y+, what method do I use to do this?
Thank you
