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.

Information of load/stress values for mesh points 12 Replies

Hey everyone!I have a pretty simple question:If I have my mesh which I analyse as a shell in karamba, is there a way of obtaining the information of how much stress forces act upon each seperate…Continue

meter vs millimeter

I wan't to have my design model in mm and structural model in meters in the same GH file. So does the scale set in the rhino file affect the accuracy of the calculations?  i.e my design model is…Continue

Karamba hasn't updated to the most recent GH build.  Use build GH 0.8.0013.  I would post it here, but there if a 5mg limit.  If you have an FTP or something I can post it there.  If you use GH frequently its good to keep a copy of all previous versions.  These things are common.

Hello David, we will update Karamba as soon as possible.

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?

hello... just installed the latest build but the icons on my GH shelf are not showing up, only in the drop down lists. normal?

thanks for your reply.hope it will be as powerful as the general fea software, such as sap& midas. good job. i am learning it now.

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.
