Kangaroo 2 for Tensegrity Structure and K2 Engineering analysis

Hi all,

I am trying to do a K2 engineering analysis of a tensegrity structure from Kangaroo 2. My primary question is that if I didn’t apply any self-weight, the k2 solver can converge to a valid solution with a good amount of internal forces. However, once I start to add only 10% self-weight of cables and structs (really small compared to internal forces), the entire geometry would collapse. (Which I believe not the case for a real tensegrity).

Any suggestions will be appreciated!
