"This looks very impressive. I'm imagining the possibilities of combining this wind force with Galapagos to find a building form to minimise overal wind loading (base shear) on a structure. Exciting stuff."

"hi nick, thanks for ur work. I just tried to open ur .ghx and notic that it was created by GH version 0.8.0003. Which means with new version 0.8.0010 occurs errors to open.   Can u please up load ur ghx in new Gh-Version again? It would be very…"

"I fixed the Kangaroo part of the model for you. - I exploded the polylines so that Kangaroo sees each of the line segments separately - I put it through a line component before the geometry input which seemed to keep the geometry output happy -…"

"It would also be really interesting to understand the difference between the different solvers and the best ways to use each of them."

"Sorry for the slow reply. It was an insanely busy week last week. - The main thing i did was flatten the Force Objects input. - There was also a Crv box that was messing up the input for the diagonals. Don't know why, but it wasn't…"

"Fixed. I also added a force so that you can put some compression in the arch and see when it becomes unstable. Now you have an arch that can move the interesting question is what shape do you make it and how do you automate the actuatoors to get the…"

"That's going to take some reading! I've never seen that method before, and i've certainly never seen it used before. It must have been quite 'out there' in 1962. His structures look very organic, which certainly can't…"

"Yes, I've seen the trick to getting Kangaroo to talk to Galapagos before. I was shown it by James Solly a while ago, who i'm sure was probably pointed in the rght direction by you! Here's a file i posted where i was trying to optimise…"

"I had a look at ways of iterating the stiffness this week. You can write to files by streaming the data from the yellow text boxes then read the data back in using the read file component. However, like you say, this seems like a slow way…"

"I'm pretty sure it works with whatever units you want it to but you have to be consistent. So, if youve drawn your model in m then you have to use m for your length scale. If you then want to input forces as kN then you need to make sure that…"

"On a similar topic, has anyone managed to create a feedback loop in Kangaroo so that you use the forces to alter the input? What i'm thinking is that you calculate the forces at the output and then use that to change the spring stiffnesses at…"

"The springs behave like..... springs! So they obey the relationship F = kx (Force = stiffness x extension). The way i've got forces out before is by finding the extension of each of the springs (Final length - initial length) and…"

"With file!"

"This probably isn't the best thing to start with but you might be able to work your way through it. I'm assuming that you're talking about using Kangaroo and Galapagos together rather than just advice on how to use one or…"
