2D elastic properties calculation with DPGEN autotest

[floatingCatty]

Are there any specific settings that are different when conducting elastic calculation in 2D versus 3D materials using DPGEN autotest?

I try to conduct calculations on GaN and borophene, but the result doesn't match the results in the literature, so I think there might be something I don't know.

Please give me some examples of this if possible, that will be a great help. thanks!
