[Gmsh] Something missing in msh file

[Henk Krus]

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!
Henk
