Hello !
How are you ?
I am an old (heavy ?) Rhino user and currently generating a collection of 3d-scanned objects.
— Is it possible to use a finite element method with meshes made from triangular vertices instead of hexahedric ?
Thank you !

Hi Oliv,
if it can help, Gmesh (linux) can do triangular vertices meshes which may be used for finite element methods.
All the best.

Hey Fred !!
Thank you for your answer !!
I am exporting triangular vertices meshes from Rhino as STL files.
I then convert them into MESH format using Gmsh (super: http://gmsh.info).
Finally I want to import them into Modalys. But I could only import hexahedric meshes using the command:
(setq coco (make-mesh 'read-from-file “mesh_from_gmsh.mesh”))
PS: .MESH files can also be .MODAL ones.
If I read the Modalys documentation more carefully (Finite Elements.pdf)… It is specified that it only deals with hexahedric meshes.
Hello to all — Was there any resolution here?
I’m also attempting to use Gmsh for mesh creation / conversion. I’m unable to convert triangles to hexahedra in Gmsh, though. If anybody has a suggestion, please let me know.
Many thanks! —
Louis
You can here find some info that may be useful for you:
Hi everyone,
Sorry to catch this that late!
1- Quads should work as well as hexahedra 2- Triangles will be best avoided!
Could anyone provide with a questionable .mesh file generated by gmsh? I recently came across a similar problem due to some dialectal idiosyncrasy (worked around in Modalys 3.6 beta ).
Also you should know that 3.6 beta now imports .obj although this is not quite documented…
Thanks, that would help a lot!

Hello, I had a successful result with MeshLab : tri to quad by smart triangle pairing
I’m using Fusion 360 —> creating a mesh, exporting to OBJ —> then converting via MeshLab
Hi,
A great and solid (and free) alternative is Instant Meshes: igl | Interactive Geometry Lab | ETH Zurich | Instant Field-Aligned Meshes
All the best,

Dear Antonio,
Yes it is !
Late thanks !
