GiD only generates hexahedral in structured form (volumes with 6 faces).
They are not directly readed the mesh format of Wavefront or Maya, but it is
simple to translate them to the own mesh format of GiD.
GiD can be customized to export the mesh, materials and conditions in a user
defined format.
Think about the possibility of modifying your FEM code to work with
tetrahedral instead of hexahedral (the tetrahedral is much more flexible at
the time of defining a generic shape)

Subject: [ GiDlist ] Hexahedra Meshing + Import .OBJ files
Hi all,
I learned about GID yesterday on the Meshing Research Corner.
I am looking for a Hexahedra Meshing Generation Software to generate
an assemblage of eigth-node brick-like elements from a triangle mesh.
Later I will use this assemblage of brick-like elements as an input in
the
non-linear finite element model that I am developing to simulate soft
tissues.
I would like to do the following with this Hexahedra Meshing Generation
Software:
a) Import triangle mesh data possible using .OBJ format (Wavefront and
Maya format)
b) Generate the hexahedra data representation
c) Export hexahedra data representation in such a way that I can
represent
in my internal data structure
I know that .OBJ format is not supported by GID. I believe that I can
write
my own personalized format reader.
I saw some examples in the tutorials and in the manual about tetrahedral
meshes.
I will go over this documentation in the weekend to see if I can find
something
more specific regarding Hexahedra meshing.
At this point I have 2 questions:
1) Can I perform the steps a, b, and c described above with GID?
2) Is there any kind of limitation to perform the steps a, b, and c with
GID?
Thanks a lot for your attention. Any pointers regarding my questions are
more than welcome.
All the best.
