[Gmsh] Very thin elements on surface (slivers)

[Alexander Tismer]

Hello,

I try to mesh a volume from an existing STL file. I always end with very 
thin elements located at the blade surface in the volume. After spending 
some hours on the gmsh and tetgen manual I spotted that these elements 
are probably slivers.

How can I prevent the creation of such elements?

Please find attached the GEO file with its STL file and two example 
pictures showing the badly shaped slivers.

Many thanks
Alex
