cross-flow fan

Moke

Dear all,

I am trying to simulate a cross flow fan using the sliding mesh capability of fluent. I am faced with a problem when I set the B.C for the fluid zone arround the rotor. I could give it a sliding mesh with an rpm (same as the rotor) but the fluid motion is in a different center of rotation (an eccentric vortex eye)which I couldn't predetermine. Any one who has an idea please help me.

Thank you very much Moke
