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.

Shell analysis of boxes.

Hi. I'm creating a system with boxes stacked on eachother. A think I got the model to work as wanted, but when changing the shell thickness of the structure with a gravity load it doesnt change the…Continue

Karamba does not appear to be working in the latest build of Grasshopper.  Are there plans to update Karamba for future use?  I have been using it quite a bit and would greatly appreciate any help that Karamba can give.  Thanks!

Try to select 'Show All Components' in Grasshopper menu 'View'. Does that help?

Karamba is an interactive finite element program for frames and trusses.

is this addon something like sap2000 component? for frame structure ?

A simple definition using the 'BESO' and 'resulting element forces' - components of the latest release to evolve a topology and get evenly distributed axial stress.
