MRF help please
 

Dear friends, I am handling rotating flow. For that I am using MRF. I have one outer, one inner cylinder rotating with a differential speed of 58rpm. In between one helix is also present. When I did not used the MRF, the angular velocity distribution is quite different than the angular velocity when I used the MRF. Can any one tell, why sudden change in angular velocity distribution??? Please i am waiting for ur reply. Thanks

Waht did you use beside MFR, is it sliding mesh? Is the difference very big?
