How i can get rid of that in Fluent when Check Case? It shows "Review wall motion. Stationary wall motion relative to adjacent cell zone detected".

I have two domains for my simulation of Horizontal axis wind turbine. one circular domain around the rotor and the other rectangular shape around the whole model which has equal distances from the top, right and left of turbine rotor when viewed from front.

I defined inner circular domain frame motion with rotational speed of 2.47 rad/s. And outer rectangular domain left it with out frame motion definition (0,0,1).
In boundary conditions, i considered the outer rounded sides of inner domain as my interface between the the fluids. And i considered all other walls of rotor, blades and with their inlets and outlet sides as moving walls with rotational speed of 0 rad/s.

Can pleas someone tell me what is wrong with my that boundary definitions to get rid of that errors??
