Particle tracking - Domain interface / FrozenRotor

mohanrao

Hi all, I am using CFX 11.0 to solve the particle in stirred vessel which consists of the two domains- 1.Rotating 2.Stationary. Frame change: Frozen-Rotor is set at the domain interface. I injected the particle in rotating domian, and set the Expert Parameter for 'pt in absolute frame' as 't' needed for RFR. Solved the particle for few seconds. I post processing of the particle trajectories I was surprised to see the discontinuity in the particle track. For example: the particle moved in the direction of impeller rotation in the rotating domain, But it came out from the other location at the domain interface. Thus I found a break in the continuity in the particle track. I am affraid this is not the limitation in the CFX 11.0. If anyone from you have come across this problem please write to me.

Thanks a lot for you time.
