Pump Simulation

Dear,
I did a simulation of a centrifugal pump in CFX, but I used it in SETUP
"No Slip Wall" with the "Wall Roughness" option Smooth Wall, my initial purpose was to compare the difference of two materials: nodular cast iron and stainless steel AISI 304 polished, the theoretical roughness values I possess, would be correct in SETUP - Wall Roughness select ROUGH WALL and enter the value? It is the same with the pump diffuser, if it is correct I will compare the two theoretical curves that will be generated.
Thanks

Yes, that sounds correct.
