[Gmsh] quadrilateral / hexa elements

[Dima Sorkin]

Hi.
 I want to use gmsh to create meshs for fem analysis with deal.II .
Is there a way to make gmsh generate *only* quadrilateral (2d) and
hexahedral (3d) elements ? I have experimented with "Recombine Surface",
and there are anyway triangles/tetrahedras remain in the mesh.

 I do not use complex meshes.My typical mesh is a 3d/2d ball,
or a 3d/2d shell (ball with an empty cavity ball inside).

  Do you have some template files that can be directly used by
adjusting parameters ?

 Thank you.
   Dmitri.
