Dear all,


how to add rotating region in an assembly of centrifugal pump.... I have casing and impeller as a assembly file. Should I add rotating region in inpeller's part file of should I make it as a seperate part. Also what should be the average size limit of rotating region which covers the impeller.


I have tried using global rotating region and used real wall cindition. But the solver stops within 10 iterations with a note "solver has stopped......"
