algorithmic modeling for Rhino



Karamba is a parametric structural engineering tool which provides accurate analysis of spatial trusses, frames and shells.

Current Version: 1.2.2 (October 6 2016)

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.

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.
