Convergence in Rotating Reference Frame
 
Hi,

I'm modelling a propellor-like problem using a rotating reference frame. The blades of the propellor are at a high angle of attack, so I expect seperation, but the flow remains attached. I've a feeling this is because the flow is not converging enough - I can't get my residual for continuity below 1x10e-3, which isn't good enough.

Can anyone tell me how I can get the problem to converge? I'm using a laminar flow model, and velocity-inlet boundary conditions. The flow is doing what I want it to do - i.e. it's rotating - but doesn't seperate.

Thanks,

Peter Wilkins
