One or more entities failed to mesh. The mesh of the bodies containing these entities
 

I am trying to mesh a 3D wind turbine blade in ANSYS MESHING.

I created the 3D wind turbine blade with twist by using the rotation command at the aerodynamic center of the airfoil .

I also created a C type domain around the blade and extracted the blade using the Boolean technique.

I keep getting this error whenever i mesh the domain .
Whenever to see show the problem, it indicates red on the edge of the geometry. I have changed the blade dimensions but to no avail. I am using 2 sections of NACA 64-618 at the very tip of a NREL 5MW wind turbine.
