About mesh division

[wen1834750]

Hello, thank you for your excellent work. I'm particularly interested in the meshing aspect. I understand that when the Reynolds number reaches around 4000, the flow becomes turbulent, characterized by numerous small, chaotic eddies. At this point, using your Gmsh template file, by increasing the accuracy to achieve a finer mesh, will this accommodate the turbulent flow? Is there any difference in performance compared to adding three to five boundary layers around the cylinder? I hope you don't mind this potentially simple question. Thank you!
