Finite Element : using triangular mesh vertices instead of hexahedric

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 !

O.

Hi Oliv,

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

All the best.
Fred

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.
