[Gmsh] 3D interconnection of structured and unstructured grids

[Trimarchi D.]

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 ;

 Regards,
 Ruth

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
