Hello Everyone,

Can anybody throw some light about the theory behind the solid domain rotation inside fluid specially the cylindrical solid body rotating inside fluid ?
I know CFX 11.0 does that by using beta property. However as it is beta they didn't give theory in the solver theory.pdf.

Kindly help me out to understand how problem solving for solid mandrel rotating inside fluid is different than fluid side interface boundary is rotating keeping solid domain stable as we used to do before this beta property was introduced.
