Hi everyone,

I am trying to simulate radial fan which using in electric motor, my mesh quality is okey(also i checked the y+) and i checked the solution with different mesh but i have a some backflow when stream close to the mrf region (also i solved with sliding mesh), back flows are not real because i am not seeing in the experiment, has anyone faced same problem ?
