[Gmsh] Quadrilateral meshes

[diagne ababacar]

Dear All

  I am a beginner in using GMSH. I would like to generate
meshes based on quadrilateral cells. How could I do it
using the GMH software. I have tried (enclosed file)
but I could just generate triangular cells.  

Any help will be invaluable for me?


Best Regards.
