Reply To: Tutorial or Help for 2 way FSI

[ashishkumar.gupta]

I guess I might have confused you. I have idea but I am not an Ansys Product expert (especially I am newbie to Fluent and FSI).

So, In Mechanical, I apply Circumferential Disp. to IR (in contact with shaft) (alternative to Rotational Velocity of body). The OR is fixed. Force is also applied to IR.

This IR moves the ball  because of Frictional contact around its own axis as well as along in the orbital motion.

 

This concept was extended by having 0.1 mm (0.1 um in future) lubricant film between Race and ball using FSI. So the displacement transfe looks like this: Race --> Lubricant --> Ball.

this is my expectation. 

But the mesh deformation of fluid and mech. at FSI is difficult to understand. That is why I was looking up for some clarity.

I have heard that Rotational Velocity is used using Joint for Ball bearings. .,..> Do u think without using joint, Rotational Velocity can be applied to my Periodic model and it will solve my other issues?

For my case, someone suggested Disp. will be helpful. that is why I proceeded with this.
