[SOLVED] AngularSpring Problems

[Edd]

Hi there,

I am attempting to model a basic mass-spring system by linking a line of particles with linear springs, and then spherical joint springs connecting each link together. I am very new to SOFA and hence apologise for the simple question.
I have created a set of linked particles using linear springs (attached code), however when I attempt to add angular springs I have difficulty in getting anything to work.

Am I modelling this problem correctly, also am I making stupid mistakes as to why I cannot function these angular springs.

Any help would be greatly appreciated, thank you!

HI @eddhoare

This topic is marked as solved, while you have not received any reply.
Is it really solved?
