[Gmsh] Trouble meshing 3d shape in "wind tunnel"

I am pretty new to CFD in general. Just starting to figure out
gmsh in order to run some simulations using ELMER. I need to put a 3d
shape inside of a wind tunnel. I have created the shape in Rhino 3d
and finally have success with importing to gmsh as a STEP file (IGES
gave all sorts of little holes in surface). I have tried and tried to
get a 3d mesh of the volume inside the "tunnel" and outside the shape,
no luck. I am sure that I am missing something basic. Can someone
point me in the right direction. I have lastly tried merging a STP of
the "tunnel" with a STP of the surface, but can't get a 3d mesh of the
inside. I get a self intersecting error. I have successfully used a
half model (like symmetry), the surface and tunnel are joined at the
middle. I would like to have my surface suspended in the tunnel
though. Thank you very much!
