Hi All,

I am having an issue with a rotating region in my study.

I have a stator (the outside housing), and an impeller. The impeller has been fully enclosed by a revolved cylinder and it is not merged to the impeller. It is "hid" in the attached images.

The problem is this:

When the rotating region option is turned off in general settings the water flows through the impeller no problem.

But when the rotating region is turned on water is not flowing through the impeller.

Please take a look at the images attached to understand.

FYI, in the component control i have the non merged cylinder enclosing the impeller turned off from the CFD analysis.

Can anybody help me out????

Thanks,

Brendan.
