I am having issues in the convergence of my residuals. My criterion at x,y, z vel, k and e are set to 1e-5 and continuity set to 1e-4. K and continuity cant even reach 1e-5 and 1e-4 respectively. May I know if the transition of my meshing from one domain to another is good? If not, what are your suggestions? I am using non-conformal meshing. I attached the figure of my meshing.

It's bad. You're aiming for a similar size cell on both sides of the interface. It's possibly OK purple-pink in the inflation region, but that's about it. There's also no where near enough resolution to pick up the wake region.

Thank you for your reply Rob. My meshing is non-conformal. Do you mean I will apply share topology? 

[Rob]

No, you need to manually set some sizing to ensure the stator regions have a similar cell size as the rotor.

Thank you rob. Ill try to change the size cells. Do you mean like changing the facesize elements in the interfaces?

 

[Rob]

Yes. You need to have a similar cell size on both sides of the interface.

Thank you sir for your suggestion
