Hi,

Thanks for the reply.It was  an attempt to see how far can I go with the form finding using karamba for my master thesis .I was trying to simulate core material.I discovered It is not realistic to do this in grasshopper since that needs professional fem software "3d meshes ".I am now using Autodesk robot to simulate different iteration of the model to prove it works first.Then I will look if it is that important to use the interface between grasshopper and the fem software.I would appreciate any advice from you.I am also looking for buckling analysis to evaluate modes to refine my design for modal displacement and deflection later on. 

Hi,

I am trying to get an inner structure for a shell design that I am designing.I have tried this simple unite using the shell element in Karamba but the results are far beyond expectation.My reference was the waffle gh file in the examples.for the inner structure.The meshes are fine the first image shows the millipede solver result.So the problem is not a mesh problem and not a material problem because I tweaked the materials with no improved results.is it a shell element problem that I don't know ?? 

The backed image shows the inner walls without the outer ones although the outer ones are included in the calculation.

Hi Karamba,
I know that all of you are quite busy and trying to help users as much as you can.
As was just wondering if you could take a look at thistopic related to buckling of members in Karamba. Robert started replying but, he might be busy until the end of the week.
So if you have some tiny amount of spare time, I would be very grateful.

Danke.
