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.

Hi All, 

this is not the place for discussions, comes a bit unhandy.

Please move to the forums!

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...

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.



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)

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

Comment by Andrei Raducanu on April 18, 2015 at 3:03pm

What I don't get is why in the simply supported plate and beam examples one of the ends doesn't move horizontally when the beam/plate gets bent.

It does have the freedom to do so and in order to keep the length constant it should do so, yet it doesn't. Please answer if You can

Can curved folding simulations be done using Karamba?
Something along these lines :

Comment by karamba on April 15, 2015 at 12:03am

Elisa, you could try to place two elements in the same spot. One with, one without eccentricity and add corresponding loads to them.

Best, C.
