[Gmsh] specifying 2nd order points

[Geoffrey Bomarito]

Greetings,

    Currently I am in the process of writing a re-meshing code.  My process
includes extracting surface elements from my model and using these surface
elements to construct surfaces in gmsh.

  My problem is that I want to keep the surface connectivity that I input
(which is 2nd order) and generate a volume mesh from that.  I can generate
meshes using my suface mesh but gmsh seems to add points/elements to the
surface.

  I am currently using splines to describe my surfaces.

Thanks in advance,
-Geoff Bomarito
