I get this error from the solver, guess it something net frame something any idea on how to solve it ?

@Juan - You can use the Length component, with the target length set to zero for the equivalent of the old springs component for tensile form-finding. The next release will also contain a membrane element.

That are amazing news! Thank you for your work Daniel, kangaroo already allowed us to create immaculate tensile structures...

Hello Daniel,
I have used your origami cluster for a simple origami. However, my mesh keeps on rotating once Kangaroo Physics is active, unlike your example. Is there as solution please?

Hello Daniel,
I'm new at Kangaroo and I've a problem whenever i try to run one of the example files downloaded with kangaroo I get the error shown in the attached screenshot, can you help me with this please?

Hi All, I have a problem with a surface I'm designing (see screenshot attached). Since the surface height changes, the height subdivisions (V coordinate) of the diamonds make the diamonds irregular. I want the diamonds to be as similar as possible in size.
Any help/ideas would be appreciated! Thanks!!

Hi Daneil, I use your definition and add string force to it because i want to make the folding surface into a cylinder shape.But the shape doesn't look like so round , so i want to add one more string force after the surface has already been folded, but it didn't work, the error message is solution exception.
Hope someone could help me !!!

Hi All, I got a new computer and tried installing kangaroo but the tab does not show up in gh. I"ve tried placing the files in this directory:
C:\Program Files\Common Files\McNeel\Rhinoceros\5.0\Plug-ins\Grasshopper (b45a29b1-4343-4035-989e-044e8580d9cf)\0.9.76.0\Components
I've also tried placing the files in this directory:
C:\Users\MYNAME\AppData\Roaming\Grasshopper\Libraries
I"ve checked the security settings on the files. They are not blocked. Any ideas how I can resolve this?
Cheers,

Hi Daniel
I am excited by your kangaroo 2, thank you.
Trying to define goals to infate a mesh, I came across your Vertex_areas_comparison.gh.
I added a 4. way witch uses the crossproduct which gives me the force_vector as well.
With that I defined an InflateMesh goal, which gives me good results for regular meshes.
The idea is just moving the face_vertices by the force_vector and let the solver add the vectors at a vertex.
Could you please have a look and tell me if I correctly handle that goals.
That would be a great help for further experiments.
Thanks again!

Daniel,
Is there a way to measure kinetic energy of a system in Kangaroo 2 as in Kangaroo 1? Just trying to figure out if a system has reached equilibrium, keep up the great work.

hi this is matthew and i just got into grasshopper learning for my design course and i have been experimenting with kangaroo. currently i want to make a shape such like this but i don`t know where to start can someone who knows how to do this please give me some ideas. thank you all for reading this. http://theverymany.com/propos-specus/12-tree-house/

Hi everyone,
I am currently working with Kangaroo simulating fabric relaxation through surface springs derived from mesh edges.
I am wanting to add additional springs to the surface through drawing curves onto the surface. These springs will have different rest lengths etc. to the mesh edge springs, therefore causing the fabric to relax non-uniformly. (similar to edge cables, but they run through the fabric rather than around the perimeter)
I am having a lot of trouble adding these springs and my deadline has really crept up.
Fabric%20Relaxation.gh
Below is an attempt to illustrate... Blue lines= Springs to add to mesh (Red).
I have attached the GH file if you can, please please help.
Thanks

Does anyone have any ideas for how to create a vortex force in Kangaroo2 similar to the component in K1?
Oct 20, 2016
Manuel
in kangaroo 2 anyone know how to recreate "geometry in" and "geometry out" from older kangaroo solver?. Its possible?
example: when remove duplicates lines/points its use for goals, but then you need to reconstruct original geometry.

Manuel, look for the "Show" component.

I have tried to download some definitions in the example page you linked, but when I open them I always miss some nodes because I have a newer version of GH and Kangaroo and the definition won't work (I have both kangaroo physics and kangaroo 2 but it won't work anyway).
For example when I open this one I will see this algorithm, what's missing??
Can anyone with an older version of GH can link me a screenshot of the correct algorithm?

I am working in a nodes project for 3d printed structures and its difficult find a smooth transition between the branch and the joint with springs force .
I am trying to improve the tangency between the the final mesh at the anchorpoints and each branch direcction rest lenght in springs force.
At the same time avoid the mesh to go in a convex direcction and have a smooth transition.
How we can find a definition , where the are diffents settings from rest lenght and stiffness to find a correct mesh ? i tried to apply unary force in some points to the mesh in every anchorpoint without success
this is de example that i work with
this is what i get normally , with rest lenght and stiffness settings
this is my goal , where there are a smooth transition in every branch direccion
thanks !!!!

i have a new examples with kangaroo 2 ( soapfil , anchor and tangential smooth ) and laplacian .
in kangaroo 2 is easy to control a mesh tension but is more difficult to have anchorpoints control in the naked edges .
this is the example with kangaroo 2
this is a example with laplacian .
For produce a differents solutions than "Minimal surface" with kangaroo 2 or solutions with "Springs" from kangaroo we need to find a specific force that push the Mesh vertex points to the fix anchor points in the naked edges .
thanks

Hello everybody, few weeks ago I've seen some attempt to reorganize grasshopper code into a readable clean manner using kangaroo, like transforming spaghetti code into clean linear code, but I just can't find it anymore. Any info about this? Thanks in advance.

That post about organizing the canvas was by me. I have progressed this work quite far, but have not used kangaroo for this so far.
If you're interested, I can send you a prototype of the tool. It is functional, but may need some improvement.

im trying to use the grab component without big success https://vimeo.com/118721449 . following the video (and also another example file > http://www.grasshopper3d.com/video/kangaroo2-planar-quad-mesh-editing ... not working as well)
help :)

Hi AJ, can you describe in what way the grab component is not working? The more detail you can provide, the more help you'll get! What version of Kangaroo are you using? What error messages (if any) are you getting when trying to use the grab component?

Hi everyone, I've a simple question. Is there an equival component for PowerLaw in Kangaroo 2?

Hi all, where does Kangaroo define literally the mass of springs? The thing is, when using Kangaroo, there is no mass input, and if I applied force=0 then displaced the support, why the structure vibrates when there is no mass defined anywhere?
The second thing is that, when I applied very high value of stiffness, with proper support conditions, the elements fly off to there screen (displacement=infinity=null), even if there is no force applied, anyone know why?
help :)

Hello everybody! I am having this problem, I already installed Kangaroo 2.4.2 and the library appears in my GH canvas. However, it seems that a couple of components weren't loaded correctly or I don't know what happened or what can I do.
Thank you so much

Hello! Does anyone have any documentation on how to use the "support 6dof" elements?
I have created a little code consisting in two beams forming a right angle which is pulled at 45° from its vertex. To goal is just to get used with Kangaroo elements and so on.
For some reason I don't really understand, when using the support tool, the nodes act as they were not constrained and free movement occurs. To bench mark it, I have taken the same code and used the "anchor" elements instead and it works quite well, so I'm pretty sure there is an issue with the "support" element.
If someone could help me out it would be greatly appreciated it.
Thanks
PD: Below I'm attaching the two files (one where I use anchors as end conditions and the other using "support" elements)
