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.

Karamba3D Joint Error 5 Replies

Hello. I’m trying to make scissor structure on grasshopper using karamba. When I want to define joints in assembly, it gives me an error. How can I define connection of the elements with revolute…Continue

Comment by Kaz on March 27, 2014 at 2:41am: it would be better to test full version , thank you for your cooperation , here is my email : blumen.sy@gmail.com

thanks again

Comment by Karamba3D on March 25, 2014 at 1:31pm: Dear Kaz, you can run the examples them with the trial-version by decreasing the number of elements or use the free version when only beams are involved. Alternatively I can send you a one-month trial license for the full version.

Best, Clemens

Comment by Kaz on March 25, 2014 at 10:48am: All examples files are restricted in trial version , how to test it ?

Comment by Mahdi Soheyli Fard on March 19, 2014 at 8:08am: Hi there,

long time no comments!

Dear Clemens,

This is actual proper that karamba have some rules for defining the relations between components, from points to lines, lines to surfaces, surfaces to forms and volumes and so on. except from manual which you've released before, is there any references you know, we could adapt our models to, for writing algorithms more accurate?

Thanks,

Mahdi

Comment by Karamba3D on January 12, 2014 at 11:26pm: "karamba.ini" is located in the folder "Karamba" which can be found in the installation directory of Karamba.

Comment by qiushi on January 12, 2014 at 2:27pm: The result of karamba analysis is too big compare with my grasshopper model even after I reduce the radius, can I change the unit of karamba to make it proper? I tried to look for the "karamba.ini" mentioned in the booklet, but didn't find it.

Thanks!

Comment by Iasef Md Rian on December 17, 2013 at 10:06pm: I am trying to analyze the structural behaviors of a brick masonry vault and a masonry shell structure. In karamba there is no material property of brick masonry in the material list. How can I solve this problem?

Comment by qiushi on December 17, 2013 at 4:04am: I make it!

I type the installing path like this:

Comment by qiushi on December 17, 2013 at 3:50am: Now I have rhion 4 and rhino 5 32bit & 64bit both. I installed karamba 1.04 for rhino 64bit free version in my grasshopper for rhino 5 folder, it does show in the grasshopper folder, but when I open rhino and grasshopper, it doesn't show on the tool bar and I didn't find the Draw All Components in Grasshoppers View-menu mentioned in the Karamba installation booklet.
