[Gmsh] Sharp corners and physicals in .stl

Hello all,

I have two issues I require help with.

Firstly, I am trying to mesh a MVG (see attached file) to use in OpenFOAM.
I tried making both unstructured and structured (dividing the doain into
blocks), but with no success: the mesh near the leading edge of the MVG is
always of very poor quality... Does anyone have any idea on how to solve
this?

Second issue, I noticed that when exporting a mesh to .stl the physical
tags are not preserved and everything is saved as a single object. I was
wondering if there is a way to do this without changing the code. I noticed
there is already the option to save all entities but it seems like this is
always triggered, no matter what.

Thanks in advance!
Felipe
