Hello,
I have structure like this and i’m interested in where it will swing, if at all.
I’ve made sure that the profiles meet in common points.
However, when I run the simulation, all outputs switch to null.
To setup all the profiles, I’ve used K2-Eng (From github). It handles units.
I’ve tested a simple case - one beam on two cables - and that worked.
Any idea why that it fails?
How do you input the goals into the solver?
I’ve tried connecting the goals to a new solver component and got this error:
Solution exception:One or more errors occurred. (Index was out of range. Must be non-negative and less than the size of the collection. (Parameter ‘index’)) (Index was out of range. Must be non-negative and less than the size of the collection. (Parameter ‘index’)) (Index was out of range. Must be non-negative and less than the size of the collection. (Parameter ‘index’))

This should have everything important internalized.
I cannot help due to these plugins.
I already moved your topic into the kangaroo category and if you don’t mind, I think it would make sense to replace the kangaroo-2 and kangaroo2 tags with k2eng.

I think I’ve removed everything. Now it works for a bit and then collapses into an angry ball.
Thank you for your help.
Ok, so I assume that structure is stiff and keeps its shape.
To use the rigid body goal, you need to create a brep or mesh. To have a quick result, an easy solution is to pipe the lines and shrinkwrap everything into one mesh.
You could also use the rigid point set but then you need to rebuild lines or a mesh after the solver.
The rigid body goal accepts points which will be attached to it. In your case, these are the three points where the lines are attached and the two points where you apply the force.
