Turbo problem
 

Hi guys,
I have a warning messge like 'WARNING
Cannot initialize component 'Rotor' in domain 'Rotor'.
Please verify that the rotation axis and turbo regions are set correctly.'

Now i'm trying to get a result through a centrifugal pump impeller and sometimes, i got same message maybe 10 times..!

I have no idea to solve this probelm and please tell me what can i do for it ;(
Thanks
