Sliding mesh
 

I had try to model a fan using sliding mesh, and the result showed that the fan was rotating but the air flow did not past through the fan. Can anyone give me an idea or advice in solving this problem? Thanks.

check your mesh around the interface, which is supposed to be continuous along the normal direction.
