Dear friends,
I am solving a problem which has a shaft ( rotating), fluid (which is rotating due to shaft motion) and a bearing (stationary). The problem is similar to journal bearing simulation. The lower layer of the fluid is attached to shaft surface and upper layer is attached to bearing surface. How to solve this problem? Do i need to use multiple reference frame or sliding reference frame? how to define these motions? The problem is in 3 dimension.

Kindly help.
