split the circle in the middle to generate an O-grid. For the mesh in the central part you could mesh each edge separately.

Hi,

Your every thing seem ok, here are few things that you need to do,

1: For outer semi circle region (extreme left) use double sided successive ratio for both small and large semi circles with appropriate same value for Ratio 1 and Ratio 2

2: For 4 end straight edges (extreme right) use same successive ratio and make sure that all edges have arrows in same direction.

I hope this would solve your problem, so
