Hello fellow Gmsh users!
 
I'm new with Gmsh and trying to complete a simple procedure of meshing
an impeller with complete volume, with no holes. Unfortunately, my
meshing does not work properly for some reason. 
Here are my steps:
1. Open a new geo file :example.geo
2. File->Merge->Choose the STEP file *provided in the attachment*
3. Elementary Entities ->Add->New->Volume
4. Click on the impeller, and it turns ALL red, no holes, so I press
'e'->'q'
5. Check the options: Tools->Options->Geometry: Include "sew faces"
6.  Check the options: Tools->Options->Mesh: Check Frontal, None,
1,1.00,0,1e+022,2......Also under Mesh Advanced include 'optimize the
quality of tetrahedra'
 
Press Mesh-> 3D and I get a very not dense meshing and the manual says I
will get dense mesh( File: according to manual) which I can further
process with calculix, translate to inp file, then include measurements
of the impeller, then run the inp file, and then do the post processing.
 
All files are included above, and any help or hint is appreciated. If
you need any further info, I can send more pictures.
 
Thanks in advance and hope to hear from you guys soon!
