Export tetrahedron nodes coordinates and connectivity March 24, 2022, 6:01 p.m.

To give an example here [people.sc.fsu.edu] there are some test files (i.e. mesh3d) depicting how the two files need to be formatted.

Wanted to ask if anyone has the Python or Houdini SDK experience to understand how complex can be this activity and define a quotation for a consulting work.

As alternative path can be to map Houdini native .geo format into gmsh .msh [gmsh.info] format.

Generated with tet embed a beautiful mesh

I want to export it.

Asking some guidance to generate these two files:

mesh_nodes.txt contains the node coordinates
mesh_elements.txt contains the element node connectivity

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.
