I am looking to simulate a high speed centrifugal impeller. But I am having difficulty with my boundary/region definition. Naturally the impeller boundaries (blades and hub) have to be a separate region from the fluid flow if rotation is wanted.
I have tried importing the the geometric model as a part and once I have defined the boundaries I created a shell region for the impeller. This creates a separate region for the impeller allowing me to apply the rotating reference frame to the impeller only. However, I am not convinced that this is the correct way. Can anyone she some light on this?
I can attach a screenshot of the simulation if anyone needs clarification.
Please disregard this post. I have sorted the problem out and found my mistake.
