Modeling a 6 strut tensegrity
Modeling a 6 strut tensegrity
(OP)
Hi all,
I am trying to model a 6 struts and 24 cables tensegrity structure. Actually, when I assign "no compression" to my cables, it gives me a "Too many attempts made for this increment" error.
Does anybody know how can I fix this problem?

RE: Modeling a 6 strut tensegrity
That error message can be due to various issues. Without knowing more about the model, it will be hard to provide any help. For example, what kind of analysis are you performing (static/dynamic..)? , what type of elements are you using (trusses, beam, frames, ..)?, what type of loading is being applied, what are the bc's?

I think that the problem is that I did not define prestress for the cables which results in singularity in the K matrix. Do you know how can I define prestress in ABAQUS for a material?

Nevertheless, search initial conditions, type=stress in the documentation.
