Hi Felipe,
I didn't manage to mesh your geometry. I'm getting this (after 2 hours of
running gmsh):

Maybe you don't have the same error, though. I have svn revision 14842.
About stl and physicals: if you need to save only a part of your geometry,
make only that part
physical. If you want to save all surfaces, but in different files, repeating
the above with setting
different surfaces as 'physical' will probably not work because the mesh
algorithm is not
deterministic - if you run gmsh twice, the output mesh is not necessarily
exactly identical. So if
you mark one surface in your geo as physical, save the stl, then mark another
surface as
physical and re-run gmsh to save another stl, you might end up with
nonconforming output
surfaces.
Maybe you could write the whole mesh as *.msh, and then see if in the gui you
cannot remove
all physical groups but one. By that I mean that you would just remove the
physical tag, not the
surface itself. Then you could export to stl. After that, you reopen your msh
and repeat with
another surface. Not very automatic but I don't have a better idea for the
moment.
Best regards,
Martin
