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.

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

Comment by Karamba3D on July 8, 2016 at 3:14am: 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!

Comment by Karamba3D on January 8, 2016 at 10:03am: 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!

Comment by Karamba3D on September 19, 2015 at 9:02am: 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

Comment by Andrei Raducanu on April 20, 2015 at 6:52am: 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)

Comment by Elisa Cheung on April 19, 2015 at 9:15am: Clemens,

What do you mean by placing two elements in the same spot? Wouldn't that give me two separate beams?
