Add at least one or two splits to your blocking.
Maybe adjust the edges of the inner O-Grid to optimize the quality.

I agree.


I just made few splits and snaped vertices and every thing is fine. By the way, are you going to make the far field?

thank you very much Far.

yes.

at first step i want to mesh just the nozzle.

then i will create a cylinder around the nozzle,and will mesh the volume between the nozzle and cylinder.
