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.

Download the free version for non-commercial use only. In case you want to purchase a commercial license please visit us at www.karamba3d.com or contact us via info@karamba3d.com or read the manual for details.

Hi Marco,

the image is similar to the setup in the example on our website. You can adjust the element felting settings to and add additional parameters to achieve different results.

Hi All!

does anyone know how to make this kind of image?

I saw different image like this made from Robert ( Hi Robert ) but I wasn't able.

Best,

Marco

Hi all!

Karamba 1.2.0 is now available! The latest release contains a new solver that is twice as fast and uses less memory. New components such as the BESO for Shells and Deformation Energy have been introduced. The entire list of updates and bug-fixes can be found at http://www.grasshopper3d.com/group/karamba/page/new-features-and-bu.... Look out for some new examples coming soon.

It can be downloaded from our website or from food4rhino. Enjoy!

Your Karamba Team

New tutorials showing workflow between Karamba and Revit using Geometry Gym and Dynamo are up on our youtube and Grasshopper pages! The full definitions will follow shortly!

Dear all,

in case of questions please open new discussions (see above). They are easier to find and to follow than entries on the comment wall.

Best,

Clemens

Hi, Rafael! I did, but i didn't manage to get what i wanted. I used the prescribed displacement component with an input vector and a force acting on the points of the prescribed displacement hoping that once the amplitude of the vector is reached, the points don't move any further, but they di surpass the length of the vector...

Comment by Rafael Pastrana on April 20, 2015 at 5:23am

Hi Andrei, have you had a look to the "prescribed displacement" component? I guess this one will help you out with what you want. cheers, Rafael.

Comment by Andrei Raducanu on April 20, 2015 at 3:26am

Hi, Rafael,

The problem with this method is that the model won't consider internal stresses. The moving has to take place after the point is converted to a support variable.

Comment by Rafael Pastrana on April 20, 2015 at 3:19am

Hi Andrei,I guess you would need to move the point that defines the aforementioned support in order to do that.

Best,

Rafael

Comment by Andrei Raducanu on April 19, 2015 at 2:30pm

Hi all,

Is there a way to move supports by a certain distance in a certain direction?

(say i have a shell and i want to move one of its vertexes and see what stresses appear)
