GH+Kangaroo+Karamba+Weaverbird

This is a system made of springs moving under unary forces. The lines which are used as springs are converted to beams and are analysed structurally to inform the opening of the holes. This model was developed for the Simply Rhino Grasshopper Level 2 Class. It uses the plugins Karamba, Kangaroo and Weaverbird. More info: http://arthurmani.com/advanced-workshop-with-simply-rhino/

Thanks! I didn't send back the data to Kangaroo. Kangaroo changed the original grid of lines and I analyzed the resulting forces to create the opening. When moving the anchor point and under gravity, the resulting forces changed so the mesh changed...

The springs are just lines with a rest length equal to their original lengths. The lines that were used as spring are also the ones that I analyzed using Karamba. I based the definition on this file on the Karamba website.

Best,

Arthur

Comment by M NICK on November 6, 2012 at 6:27pm: Hi Arthur,

That's a great job, i'd like to know how did you send back the Karamba result to Kangaroo?
Also about how did you model springs as beams for karamba?
Could you please send me this part of your definition?
Thanks alot, it would be a great great help for me.

Comment by Arthur Mamou-Mani on July 11, 2012 at 9:24am: Done! Video replaced, thanks again Adam, I also corrected an error which I noticed: The supports (anchor points) where changing when they were supposed to be fixed (image below). This gets resolved when re-computing the definition. Strange, but what's on the video should be correct:

Comment by Arthur Mamou-Mani on July 11, 2012 at 7:09am: Thanks a lot Adam, I just double checked the file and you are right, the relationship is inverted! I have inversed the remap and will update the video ASAP. Nice one!!! Below the fixed version with the average moments in kNm per cells.

Comment by Adam Holloway on July 11, 2012 at 6:23am: Nice experiment Arthur. I'm not sure I understand the connection between the structural forces acting on your beams and and the holes though. The holes are supposed to get bigger where less structure is needed, according to analysis through Karamba?
