Karamba

Karamba is a parametric structural engineering tool which provides accurate analysis of spatial trusses, frames and shells.

Current Version: 1.2.2 (October 6 2016)

karamba is an interactive, parametric finite element program. It lets you analyze the response of 3-dimensional beam and shell structures under arbitrary loads.

karamba is being developed by Clemens Preisinger in cooperation with Bollinger-Grohmann-Schneider ZTGmbH Vienna.

Hi Balaji,

Although we don't have any tutorials relating to voronoi gridshells, the following tutorial explains how to set up a generic gridshell. You can use the same technique to apply it to the voronoi grasshopper setup.

Please note that most of the tutorials on our page are not set up by us and rather other users who have been kind enough to share them with us.

Hi Matthew,

Thanks for the answer!

Yes, I actually do have a Voronoi Gridshell in Hand, made by myself but the Thing I am looking for is to optimize it (moving the seed points) according to the boundary conditions (loads), which made me stumble upon Karamba.

Do you have any closely related stuff?

Hi Balaji, we currently do not have any specific tutorials relating to voronoi gridshells, but there are some tutorials on gridshells themselves. Otherwise I am sure there would be a wide range of tutorials in the wider grasshopper community to guide you through setting up a voronoi gridshell.

Hello Team Karamba,

I am new to Karamba and have just purchased a PRO license (waiting for activation).

I am currently working on Voronoi Gridshell structures for my Master Thesis  and came across a very relevant example on your side. The example is http://www.karamba3d.com/examples/hard/projected-voronoi-pattern-gr....

I am very interested in knowing more about it. Is there any related tutorial ? (i could not find any on the site)

Kind regards,

Balaji

If I use the last version of Karamba and I need to know the best sections of the beams do I need to use galapagos or is it ok to use the option of the best beam?

Comment by karamba on November 1, 2016 at 1:58pm

Hello Alexia, Karamba is a Finite Element toolkit and thus does not depend on national specifications. The only exeption is the cross section optimization algorithm which is based on Eurocode 3.

second order theory (Th.II) could you pls help me understand what this theory is called in Italian? is Karamba ok to do the analysis in Italy? 

Comment by karamba on September 13, 2016 at 1:48am

Hi Marco,

the image is similar to the setup in the example on our website. You can adjust the element felting settings to and add additional parameters to achieve different results.

Hi All!

does anyone know how to make this kind of image?

I saw different image like this made from Robert ( Hi Robert ) but I wasn't able.

Best,

Marco

Hi all!

Karamba 1.2.0 is now available! The latest release contains a new solver that is twice as fast and uses less memory. New components such as the BESO for Shells and Deformation Energy have been introduced. The entire list of updates and bug-fixes can be found at http://www.grasshopper3d.com/group/karamba/page/new-features-and-bu.... Look out for some new examples coming soon.

It can be downloaded from our website or from food4rhino. Enjoy!

Your Karamba Team
