Trying to create a tensegrity model in robot !

[balaceanu_catalin_23]

My tensegrity model in RSA has come up with a small problem when i try to calculate it : "instability (of type 3) detected at node in direction RZ". I don't seem to figure it out and thought someone could have a look at it and give me some insight on it, maybe help me fix it.

I think i haven't defined the cables right or something like that. If someone has the time to have a look at it, please leave me your email and i will send it to you. Thank you ! 

PS: the panel should whitstand a load of 12 kn

Thank you for taking the time to have a look. I could not manage to attach an RTD file, so i sent it by archive RAR.

Taka a look at cable definition: Cablu 4.07m -> Elongation, Relative = -1 !!!!!

For example set relative =0 or correct value.

Thank you very much ! It now works. Haven't worked with cables before and i must have understood wrong when i read about them and put -1 there !
