[Gmsh] Gmsh error mesage

[Marcela Cid Alfaro]

Hi,

   I'm using Gmsh to generate a mesh of a specimen which is a plate with a
lots of holes on it.
   The  plate and the holes are different materials, so in order to
identified the 2 different materials I defined a rule surface for the
plate and plane surfaces for the holes.
   For the ruled surface I selected all the borders of my specimen (24)
and the holes but I get an error mesage telling me that the definition
of the ruled surface is wrong.
So, my question will then be, it is possible to define a rule surface with
more that 3 or 4 borders? and if so, which is the correct procedure?

I attached to this e-mail the geo file I'm using and the error  file

Thanks!!

Best regards,
