Rotation of 3D geometry taking too long time to compute

Please login with a confirmed email address before reporting spam

I am using the rotating machinery laminar flow physics. I am trying to solve with time dependent study.
Every time after computing 7% or 4% it hangs up and continues doing iterations upto 2000 and never converges.

Another time i used frozen rotor then i got solution in 2 mins.

Can anyone look at the model and rectify the flaw.

Thank You
