Hello,
I am trying to use snappyHexMesh to generate the volume mesh from stl files. I think I tried almost all kinds of snapping settings but I cannot eliminate some triangular cells shooting in or out of the surface at the edge of the geometry. Having those bad cells prevent a proper layer addition to that part of the geometry so my boundary mesh is not completely covering.
I'm putting an example for the bad cells.
Does anybody have any idea which parameter(s) to change to avoid that behavior?
In my opinion, try to improve the quality of the stl Geometry file and try to remove thin edges by merging many surfaces together.
You can give a chance to Gmsh software. Just upload your .stl file and try different meshing algorithms.

Thank you Hassan El Sheshtawy , indeed , will focus on improving the stl file first.
I like using Gmsh when I can Mahmut Burak Okuducu but I did not manage to mesh a 3D boundary layer (e.g. corner) in Gmsh.
