A small question about facet crease stiffness

[KaiXiao55]

Dear author,

Sorry for bothering again, I am not sure to put this question in https://github.com/amandaghassaei/OrigamiSimulator/issues since it seems like that one does not have a discussion tab.

I found an interesting thing about facet crease stiffness in two different structures. And it looks like these two cases may lead to contradictive results.

Specifically, I tested a closed-loop structure (4-bar linkage) and an open-loop structure. While increasing the stiffness of facet-crease (I guess it increases the rigidity of face?), the closed-loop structure's squared-shape face becomes non-flat whereas the open-loop structure's face becomes flat.

open_loop.txt
closed-loop.txt

Are both results making sense? or my FOLD file has some problem?

I will very much appreciate it if you reply.

Kai Xiao.
