Reply To: Tutorial or Help for 2 way FSI

I was suggested that rotational velocity would not work here. I also tried that and it did not work. So I was using Displacement upto the point IR and Ball are in contact (4.3 mm Circumference).

Because if I was giving rotational velocity in Mech, the body was not responding....I wasted 6 weeks on that.

 

In Fluent, should I give wall Velocity = RPM as the B.C. ,,,right? then what about Ball and OR ? Becuase Ball will also rotate and OR if fixed but fluid at OR will move. 

Is it not possible to keep walls of Ball and OR 'Moving' without specifying 'Speed'?

 

As for Mesh quality, I will look into it and update you.
