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.

Mesh Load Unit Question 1 Reply

Hi,I have a question about the mesh load unit. It seems Karamba only extracts values from Rhino, not the unit. For example, I work with [mm] in Rhino and I have a surface of 1000000[mm^2]. When I…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.
