      Dear Experts,


      I have created a mesh of fluid domain around turbine in design modeler mesher CFX. I have not applied inflation layers around the blades and hub. The mesh quality as SKEWNESS shows maximum value of 0.85 as shown in the images attached.




      But when, I apply inflation layers around the blades and hub, the quality of mesh decreases and inflation layers produced are not of good quality.



      Please help me on this. 


      Thanks
