Default RE:Change roughness of a cylinder in FLUENT!please
Posts: n/a

I saw post in the forum below stated that to change the roughness of a cylinder, we have to go to 'define-boundary condition-momentum-roughness'

I cant find 'momentum' under boundary condition, only inlet, wall, etc.

Can anyone plese tell me the exact and correct method for changing the roughness of a cylinder in a flow please?

Really appreciate it !

Thanks Ken

If you choose wall as boundary condition a window opens where you can set the conditions for thermal/DPM/momentum..... If you click momentum you can choose wall roughness. hope that helps Gernot
