Karamba3D is an interactive, parametric finite element program. It lets you analyze the response of 3-dimensional beam and shell structures under arbitrary loads.

Karamba3D is being developed by Clemens Preisinger in cooperation with Bollinger und Grohmann ZTGmbH in Vienna.

Comment by Karamba3D on January 20, 2017 at 12:16pm: Hello Earth,

use the 'Prescribed Displacement'-component and 'InitialStrain' from the 'Loads'-component to define support settlements and pretension in elements respectively. For details see the manual. It can be downloaded from http://www.food4rhino.com/ or http://www.karamba3d.com/downloads/. Please open a new discussion in case of further questions.

Regards,

Clemens

Comment by Earth on January 20, 2017 at 11:33am: Hello Team Karamba,

I am relatively new to Karamba. I was wondering if Karamba can deal with pretension problems, or support settlement problem where the initial displacement of certain amount takes place that causes forces developed in the truss or frame members.

Kind Regards.

Comment by Karamba3D on November 14, 2016 at 7:45am: 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.

Comment by Balaji Visvanath on November 11, 2016 at 5:49am: 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?

Balaji

Comment by Karamba3D on November 11, 2016 at 2:01am: 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.

Comment by Balaji Visvanath on November 9, 2016 at 4:07am: 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

Comment by Alexia Ch on November 6, 2016 at 3:54pm: 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 Karamba3D 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.

Comment by Alexia Ch on October 31, 2016 at 2:35pm: 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 Karamba3D 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.
