Wind Turbine blade meshing in ICEM CFD
 

HI, I am meshing a wind turbine blade in ICEM CFD. I started with a structured mesh and there has been some problem in the surface mesh. The mesh near the trailing edge of the blade is getting merged(as in the images attached). I think it is an association problem but I'm having a hard time figuring out the exact problem.

Please help me out with this.

Thank you in advance :)
