Sorry Daniele, that's not possible when mixing structured and
unstructured grids.

Hi Ruth,
Yes, I agree with your remark. The question was not well posed: is there any
way to build prisms or pyramids in gmsh?
Thanks,
Daniele

First, remove the line:
Line(62) = {27, 27};
Second, it is simply not possible to get only tetrahedra when you have
squares in one of the surfaces enclosing the volume, prisms and/or pyramids
should be generated.
If you don't recombine Surface 11, you will get a mesh with prisms and
tetrahedra.

Hi Ruth,
Thank you for your post, this is very interesting. I am also interested in how
to connect structured and un-structured blocks; however I find problems when
try to connect structured hexa and unstructured tetra.
Please find attached an example where four blocks are connected. I cold'nt
figure out how to resolve the connection between the tetra and hexa.
Any guess?
Thanks,
Daniele

You can use Gmsh but you must force the Frontal algorithm.
Options->Mesh->General->3D algorithm->Frontal
You can also force the algorithm in the geo file with
Mesh.Algorithm3D=4;
Have a loop at the attached example
Mesh.Algorithm3D = 4 ;

Hello everybody,
I try to connect a structured grid with an unstructured one in 3D, without
any success for the moment... (I found in the archives something concerning the
same question, but it is from March 2000)
Can gmsh do this? If yes, how can this be done?
If no, can someone tell me if there is another tool to create hybrid 3D mesh ?
Best regards
Nolwenn
