Cartesian hex meshing issue
 

Hey everyone!

I'm trying to develop a Body-Fitted Cartesian hex mesh from a STL file, but I keep having these elements coming out of the STL surface (red lines in the picture) in some occasions.

I have tried to play around with the parameter values, but I only manage to get rid of this display when the mesh is too fine.

Does anyone knows why this happens and a way of taking care of it without refining the mesh furthermore?

Thanks!

Andre
