[Gmsh] Hybrid mesh and combine triangles in quadrilaterals

Hi,
I have two questions :
1- How do you create hybrid meshes in 2-D (quad-dominant with a few
triangles) ?
Until now, I am using the Recombine option, but often I get non-convex
quadrilaterals.
In the picture attached to this message, you can see that two elements
(in black) are non-convex
quads and that's a problem ... So, often I change the characterisc
length in the hope that I will have only
fine quadrilaterals. Is it possible to require that all quadrilaterals
are convex ?
2- In 3-D, when I try "Recombine Volume", it doesn't work. So, how is it
possible with gmsh
to create 3-D hexahedral-dominant meshes (with some tets, pyramids and
wedges) ?
Thank you for your help.
PS : I am using gmsh 2.24
