I want to perform CFD simulation of a compressor blade (turbomachinery). I have created two domains, one cylindrical for the blade and a rectangular domain for flow simulation. Meshing and all other boundary conditions proceed fine without any error. But when I run the calculation in ANSYS FLUENT, I get the following errors after 500-600 iterations :-

1. # Divergence detected in AMG solver: pressure correction-> Turning off correction scaling.

2. # Divergence detected in AMG solver: pressure correction-> Increasing relaxation sweeps!

3.# You may try the enhanced divergence recovery with (rpsetvar 'amg/protective-enhanced? #t

4. # Divergence detected in AMG solver: pressure correction.

I have run the simulation as transient one, with pressure based and laminar flow..

Following are some of my input data :-
Time step size - 0.01
Number of time steps - 100
Max. number of iterations -80
Initialization is hybrid.
Angular velocity- 50 rad/s

Please help me find a solution.
