[IMPORTANT] Propeller Meshing and Boundary Layer

Hello fellow CFD-ers.

I have been trying to achieve to Mesh as attached but I change the mesh of the boundary layer also everytime I change the mesh size. Is there anyone who can advise me on this?

What are you trying to accomplish?

Hello! Thank you very much for the reply.

I am trying to find the torque, thrust and power produced by the propeller.

Thus, I am trying to obtain a mesh that helps me to accurately mesh the blades only and not the boundary layer.

Why do you think you should not mesh the boundary layer accuratel?
