[Gmsh] Something missing in msh file

Hi all,
I'm trying to write a geometry and data out to a msh-file. First
step is to send results to gmsh; next step would be to write out
data (geometry) and boundary regions from gmsh towards dolfyn (how
to deal with surfaces is the next question; and is it possible to
import just nodes+cells in gmsh and assign boundary conditions).
As such the geometry looks ok (but hex and tet models) but I do not
see the boundary regions/walls/surfaces. Moreover the velocity
vectors nor the temperatures appear. I'm overlooking something but
what?
The structure of the msh file:
The hexahedra are fluid cells (id 1). Boundary regions are fluid+
region number. Both are 'cells' (hex+quad); data corresponds as
well. What am I doing wrong?
Thanks in advance folks!
