Created a tet mesh from an organic shape using Tet Embed and was super easy, I have a problem about how exporting it preserving the created solid geometry. This [e1.pcloud.link] is the original mesh.

Exporting as STL or OBJ is preserving the triangles but loose the information about the solids, so that if I import the STL in a mesher such as Gmsh (need to convert the result as.msh) told me there are 0 tetrahedron.

I'm not aware of any formats that support exporting tets, other than some scientific simulation formats. OBJ and STL formats can only describe surfaces made of polygons.

It's really a pity.
I'm doing the same work on specialized mesher that require messing around btw scarse or huge documentation, forum, testing to achieve something in Houdini needed just a couple of nodes and 1 min work.
A waste of potential, considering also Houdini has his FEM solver.
I.e. gmsh it's an open source mesher with his own .msh format that I suppose can be used for an exporter in Houdini.
I just needed the developer support to understand how to get out a tet mesh using his far from clean UX.
