[Gmsh] Create a Boundary Layer around a blade

[Alexander Tismer]

Hi Javier,

my case was a little bit different. I also try to put a layer on hub and 
shroud. This did not work well in my case. I always end in troubles with 
an intersecting surface mesh.

You can also try to use the PostBL tool from the MeshKit library.

Best regards
Alex
