Frukk is on a distinguished road

I was wondering how i can approximate the mesh size for a CHT Problem. I have a rotor and i want to simulate the heat transfer in the casing of the rotor. Are there any quality or other requirements for the mesh in the solid casing? and what is a good starting point to decide what size the mesh in the casing should have in comparison to the boundary layer of the rotor domain?
