OctopusLoop

Hi all,

I use Octopus in combination with Octopus loop for my graduation project.

I’ve attached the model I am currently working on. I want to optimize an arch in sense of shape and thickness of the panels. I use Octopus for finding an optimal shape by only changing the horizontal form finding forces in Kangaroo (not the vertical form finding forces to ensure the height will be the same). The objective for Octopus is given by the structural analysis, performed by Karamba.

Besides optimizing the shape of the arch, I also want to optimize the cross sections of the elements. For that, I first used Anemone, however, there is some delay in the output of anemone because of the computation time. So everytime when the loop in Anemone is still calculating, the geometry is changed again by Octopus. I read that Octopus Loop can be the solution for that problem. So in my attached grasshopper file I tried to implement the Loop into my model, however it does not run, where Anemone does run. The Anemone Loop and Octopus Loop are situated in the light blue groups in the figures below and also in de Grasshopper file.

As far I can tell OctopusLoop only does only one iteration. So maybe I connected something wrong.

Can you help me with this problem? I’m sure it is a small problem, but I can’t figure out what the problem is. If something is nog clear enough, please let me know.

Thank you in Advance!

Kind regards,

Thomas van Vooren
