Bearing and air simulation
 

I've just arrived at CFX software and I have to do some simulations urgently.

I have got a shaft, a ball bearing and an air flow go through the ball bearing. I've read something about Moving Mesh and Rotating Boundary but I don't know exactly what to do.

What can I carry out this simulation?

Is it more complicated if I add the lubricating oil?

Thank you very much.

so ,firstly i think it is not hard.you can simulate the modle by CFX. Through setting the inlet,outlet,wall and the other boundary.then the problem will be well solved.
