Blocking shematic
Split the block in 12 parts like in the figure on the left hand side! At O-grid splitting select the blocks marked with blue and the edge marked with
yellow!On right hand side can be seen the blocking after the O-grid splitting.
The filled blocks are inside the blade, you can delete them.

Mesh refining
Refine your mesh if need, for example a fine resolved boundary layer around the blade can be useful
