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.

How to define 3D Objects in Karamba 4 Replies

Hello. I have a problem in defining 3D Objects in Karamba. What I am trying to do, is that I have 3D scanned a few Irregular stones. So I have their 3D meshes in grasshopper. Then I am trying to…Continue

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.
