AnchorSpring: Constrain an anchorspring-point to a certain range 2 Replies

hello to everyone.I will find really useful to be able to constrain an anchorspring-point in a certain range from the original one during a simulation.Rightnow I can use "Sticky" in AnchorSpring to make react this component only after having…Continue

Optimizing for specified edgelengths 13 Replies

Hello everyone!Is it possible with Kangaroo to optimize a certain topology onto a surface, so it has only a few specified edgelengths?The goal would be to not have transition between the edgelengths, but approximate a few specified values as much as…Continue

Volume dependant pressure. 2 Replies

Is there an example of the volume dependent pressure in action?I plug the KGas straight into the Force objects on the solver and I get nothing as shown, and the mesh just sinks to the ground, flat as a pancake.:(Please tell me what I am doing wrong.Continue

Forces control at each anchor point 2 Replies

Hello everyone! I am preparing a form finding lecture for my architecture students and I want to show few samples using Kangaroo. My question is: How can I control the forces at each anchor point? How can I assign different forces at the anchor…Continue

Hello Daniel,

I am trying to inflate 4 balloons within a box which itself also inflates. I would like to constraint the balloons inside the box but it is not working. The external surface of the inflatable object collide with the exterior surface of other objects but not the exterior with the interior. Is there something wrong with my definition or there is another way to do it?

Any help on this matter would be really appreciated since it is part of my thesis project!!

Thanks!!!! :) mesh_sphere_balloon4.gh

Hi Daniel,

i'm having an error using KingKong plug-in, this error come from the kangaroo cluster, I think it's for the change of the hinge component in the last update of kangaroo, i'm wondering if someone can share the password for update the cluster?¿ or update the cluster and share again for continue using this nice plug-in?¿

Thanks

Hello,

I am trying to create constaint on  an inflattable mesh by using a curve as a spring. I used the mesh collide  component in order to deform the mesh following the curve as a constraint but the mesh doesn't seem to recognize it. I am working on the file that originated from this discussion.

Any help would be appreciated

Juan

thank you , it is working now.

Hi Andrés. Just make flatten at "Force Objects".

Hello All.

I am testing the catenary example, but it does not work, I have an error 1. Solution exception: Index was out of range. Must be non- negative...

somebody could explain me how do I fix it?

Thank  you.
