Hi all,
I’m currently working on an active bending wooden grid-shell (form finding and structural analysis) and I would like to have some informations about the latest version of Kangaroo, which introduces the beam component.
Indeed, until now, I have always used the rod component to find the form of the grid shell, but this component is only 3dof and don’t take into account the difference between Ix and Iy inertia. Also, to retrieve the local axis for further analysis, I have to use a patch which is not really accurate and takes lot of time to compute.
With the beam component, the fact that we can retrieve the start/end frame is much more comfortable and the form finding takes into account 6dof effects and Ix/Iy beam inertia (time of computing is also faster).
I’m posting here to get more informations about this new tool as the units of the physical parameters or the local axis of beams (for Ix and Iy) are not mentioned, and which of the beam or rod component is closest to the reality ? Also, I didn’t see any difference when changing the inertia or the area of sections. Is that normal ?
@DanielPiker can you have a look at this please, I really appreciate this new functionality and really want to work with it. Thank you !
Here are the two different script and the results (in blue with beam and in red with rod).
