Hi,
I would like to get the flex torque of a rod componants structure as an output of the Kangaroo solver (a bit like the beam componant does).
I try on a simple exemple by grabbing the node manually but I can see just the geometry as output and nothing about flex torque or even stretch of the spring ?
Probably my approach is incorrect, see the file

Thanks for your help!
I put your topic in the Kangaroo category.
You have to script the post processing yourself. For stresses use Hookes Law with the new lengths and for bending moments you can use the new curvature and use the w”(x)=-M /(E * I)
For that to work the inputs have to be in the same units. EA/L for spring stiffness and EI for bending stiffness.
If I understand, I will need to rebuild the polyline into a curve with control points and then to make a curvature analysis of this new curve.
Thank you Rudi.
It will have to be discretized into small line segments. So you want to get the “discrete” curvature. Could be done by fitting a circle in three points.
