Hello Rob, Thank you for ur response 

 

I have prepared a model with a ball, IR and OR too see the effect of Lubricant on the Hertz Contact region so as to minimise the friction and wear. From the figure, Oil will always be present between the ball & Race --> Elasto-Hydrodynamic Lubrication

IR rotates (by giving circumferential Disp.) and radial force also applied bcoz of shaft and OR is fixed ---> in Mech. Structural Transient

Lubricant inlet on left side and outlet on another. Isothermal, incompressible fluid and SST k-w model used with Dynamic Meshing -- > in Fluent

But the model does not run as there is no direct mechanical contact (in Transient) between ball and races. What am I doing wrong here? 

P.S. Mapping is 100% between ball and IR  & ball and OR. I have developed all this from the Reed valve tutorial and other documentaion.
