hi, clements,  i read karamba manual again,  during that, the eigenmode and eigenvalues still troubles me to understand,  it seems to test vabration and get eigenvalues by eigenmode. 

what is the funcion of eigenmode, and what does the eigenvalue mean?

stability?  do the eigenvalues has standard to show whether it is safe or not?

sorry,  it seems a basic structure knowledges,

right sorry for that, and thanks

Hi, I am moving all discussion to the user problems page as the parallel discussion is cumbersome. https://www.grasshopper3d.com/group/karamba3d/forum/topics/karamba-...

It turns orange because I set one point as support two times (it's part of two groups of points one group fixes the Z movement the other one fixes every movement), but it shouldn't be a problem right? at least the dialog box says so.

Anyway the problem is similar if I decimate the mesh, I think it might be a problem of how do karamba calculate the thickness of the structure, in fusion I modelled the thickness myself in Karamba I didn't maybe it's that? however I think in fusion when he calculate the mesh he also adds inside edges to keep the two layers together when deforming, in karamba I don't think it does it am I wrong?

Hi Riccardo, there seems to be an issue with you definition as it turns orange. Also, may it be that your mesh is too coarse?

Another question: I'm trying to reproduce the behaviour of these two structures that I observed in fusion 360 only using Karamba.

As you can see from the images the structure on the left have much less deformation, in Karamba they are almost the same what is happening here? The KAramba code is so much different from the fusion 360 one?

Dear xiufeng li, when internalizing structural objects in one version of Karamba3D it is sadly not possible to guarantee that they can be deserialized with another version of Karamba3D. I think this is what causes the problem here.

Best,

Clemens

Hi Xavier,

you need to update your Rhino to the latest release in order to run Karamba. The latest Karamba release can also be found on our website.

I am getting an error when trying to open a grasshopper file with kangaroo and karamba components. I am new to both grasshopper and karamba and was wondering how to better understand the error message and where I can download or access the correct plugins.

So far I am not able to find the versions of the plugins mentioned in either of the error boxes.

Thank you!
