ANSYS fluent connection
 

Hello
i m simulating part which is rotating in domain. When i create domain around my part using enclosure it creates connection. The part then interfers with fluid flowing in domain. But if i import my own domain from CAD it does not. So the part does not interfer with fluid in domain. How can i create same connection manualy as would design modeler or mesher do if i use enclosure option ?

I m using ansys 15.0
Thank you
