Confused Octopus Newbie

Hello,

I am trying Octopus for the first time; all of the tutorials and previous posts seem to have older components that make it so that the Octopus component does not load, proving to be unhelpful for me. I have read all of the forums but am still seriously having trouble understanding how this works!

I have a script in which I want to find the optimal parameters to return a geometry of a desired volume and desired surface area, or at least as close to each as I can get.

I have connected variable parameters to the Genome input and the resulting area and volume to the Octopus input. In the Phenotype I've put the resulting Brep.

Each time I run Octopus it freezes. I notice that in the Genome input, it says "empty structure" even though it is connected. Also, I don't understand how to specify what I want the volume and area to optimize to. It seems like this can be done though. Help!

Hi Yeliz,

I just updated octopus, and it should be available on food4rhino as soon as it is confirmed by an admin.

Best,

Robert

Amazing, thank you so much!

So, when it comes to selecting the objectives, do I simply set the max of the solutions, cut off, and select the closest iteration to their convergence? Is there a way to specify a range that the Objectives are within to be collected?

Thanks again,

Hi Robert...Just posting to let you know about this new error message I get when load the same script on the same computer that has all of the same versions, a few days later... (Octopus 3.4 + Grasshopper .9.0075)

Component Octopus {f0913905-0d71-4c22-b63d-60d6e6cf4cf6} failed to deserialize itself: Could not load file or assembly 'HelixToolkit.Wpf, Version=2013.1.10.1, Culture=neutral, PublicKeyToken=52aa3500039caf0d' or one of its dependencies. The system cannot find the file specified.

this is because you probably did not move the file 'Helixtoolkitwpf.dd' into grasshoppers libraries folder - should be the same as octopus.gha is placed into. so normally, goto grasshopper - file - special folders - components folder and place the files there.

best
