I have an stl file describing a complex model, I extracted some points of this

Yes, if you only read the gmsh output, you have lost information about the
underlying geometry (which was originally provided by the STL file). You need
to use a manifold to the triangulation that uses the STL file as the
underlying geometry. Most of what the TriangulationOnCAD::read_domain()
function of step-54 does is setting up a manifold with the help of
OpenCASCADE. You have to do the same, where you need to get a CAD geometry
from the STL file.
