Sometimes TetGen (the library responsible for tetmeshing) throws errors and fails to mesh, so I wrapped its tetrahedralize
function in try-catch blocks in lines 967 and 1078. Since you aren't getting error code output, and your program is failing on the first instance of tetrahedralize
, it must be line 1213 that's giving an error, though I can't imagine how since it's just meshing a simple cube with no constraints.
I don't get any errors on my machine when I run the program on your model:
This is a total shot in the dark, but does increasing the value of the scale
parameter in triangulateCube()
help? Or perhaps scaling your mesh up? If I had to guess, maybe TetGen is having numerical difficulty (though I can't imagine why since your model is a "normal" size.)
Other than that I have little clue. Let me know how it goes, and if you observe any other weird behavior!
I tried both your suggestions of scaling the input mesh and/or scaling the factor (and recompile). None of these changes fixed the crash. I will try to run this on a different machine to see if that makes the difference for me as well.
For completeness this is the error after changing the scale factor to 3. (from 2.) at triangulateCube().

Using a broken bilayer mesh with the
tetmesh
and default options causes the following error:The mesh was generated using blender voxel remesh and is well oriented. Using the grid based approach does work.
