You are right, it would be nice if Gmsh could create automatic hex-dominant meshes from CAD files... :)

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
