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.

Download the free version for non-commercial use only. In case you want to purchase a commercial license contact us via or read the manual for details.

Dear Clemens,

Could I enjoy that one-month trial license? I need to try beam joints components.

Thank you very much.

it would be better to test full version , thank you for your cooperation , here is my email :

thanks again

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

All examples files are restricted in trial version , how to test it ?

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?

"karamba.ini" is located in the folder "Karamba" which can be found in the installation directory of Karamba.

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.

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?

I make it!
I type the installing path like this:
