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 contact us via info@karamba3d.com or read the manual for details.

Here some results from calculations with shells:

Fig. 1: Deformed geometry and color-plot of resultant displacements of double curved shell under point load.

Fig. 2: Principal stress lines in cantilevering shell and color plot of material utilization.

Fig. 3: Force flow lines in disc with hole in the middle and utilization of shell material.

Comment by j koeken on October 15, 2012 at 10:26am: Hello,

I`m using karamba for my shell structure. With the analyzis

the displacements are given, the princ. stress do not work, how can

i solve this problem? See the pictures

I get the messages:

Error: Solution exception: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

Best,

Clemens

Comment by karamba on August 18, 2012 at 1:13pm: The component is missing due to an error in my compiler settings. I have sent you a corrected version.

Best,

Clemens

Comment by Kane on August 18, 2012 at 9:51am: I still cannot find it, do I have a wrong version or is something disabled from layouts?

Thanks K

Comment by Kane on August 17, 2012 at 1:39pm: Hi all, where can I find the mkset tool, or where can I get it? I am experimenting with the stitching tools for trusses and need this tool to stitch a number of truss tension members to their corresponding compression member.

Thanks

K?

Comment by Robert Vier on June 10, 2012 at 5:26am: ah,

and hinged connections you can achieve either by using the 'modify beam' component and set the 'bending' input to false, or specify it more detailed by introducing 'cross section joints' on specific beam ids where you can set the same properties as for supports for each the start and the end node of a beam separately.

Comment by Robert Vier on June 10, 2012 at 5:24am: hey djordje!

Tx, Ty, Tz represent the freedom of a support to move in x, y and z direction (T for translate). the same holds for Rx, Ry, Rz but for a rotation around the respective axis. those directions can also be determined by a reference plane other than the world xyz system.

Black means the degree of freedom is restrained, while white means it is free to move.

the symbols you see in the drawing are possibilities to more apparently visualize a special support situation, e.g. having a member on a rolling wagon etc..

you could also post requests in our discussion forum http://www.grasshopper3d.com/group/karamba/forum rather than on the board ;)
