Optimization hangs indefinitely during stability optimization

[RuiningLi]

Thanks for the amazing work!

I'm trying to play around with the script for stability optimization.

Even for a simple mesh (e.g., a cube), the optimization seems to be hanging indefinitely (I have waited for 10 minutes, 5x time reported in the paper).

I would really appreciate it if you can point me to the potential issues! Many thanks :)

FYI, this is the cube tetrahedral mesh I'm using: https://drive.google.com/file/d/1xxKxVqp4vh7aQ3PumbFoBck_IxJI2ljI/view?usp=drive_link.

Thanks for your interest! May I know how you set the fixed vertex IDs in the fixed.txt? Without fixed vertices, the cube may be free-falling forever.

Thanks for your response! I'm using the default implementation in test.py, so should be this:

min_y = np.min(tet_vtx[:, 2])
fixed_vertices = np.where(tet_vtx[:, 2] < min_y + 1e-3)[0]

May I ask what is the setting you used during evaluation on Objaverse as shown in Tab. 1 of the paper?
