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.

Comment by Karamba3D on February 20, 2018 at 1:56pm: Dear Mahdiyar,

your system is kinematic in three modes. This causes the problems. Please add an new discussion (see above) in case of further questions.

Best,

Clemens

Comment by Mahdiyar on February 13, 2018 at 3:04am: Hello,
I have trying to analyze a Truss Structure with Karamba3d.

My problem is whenever I recompute my definition, Karamba Analysis result changes significantly.

Comment by Matthew Tam on December 25, 2017 at 5:09pm: Hi Niklas,

you have to make sure to split the lines into segments at their intersections otherwise Karamba will out put errors. Also make sure to flatten the input for the Elements in the Model-component. Please see the attachment.

Comment by Niklas Haschke on December 22, 2017 at 6:06am: Hey there

I am quite new to Karamba and would really need your help.
I am trying to analyze the structure for a new priject and I am struggeing with the supports (always the error: could not find node at ...)
Could someone have just a short look on that?

Thank you

Niklas

Comment by Karamba3D on October 25, 2017 at 12:59pm: Hello Wanggian,

in order to make the warning disappear you could change the upper limit of the cross section height from 65cm to some larger value.

Best,

C.

Comment by Wangqian on October 25, 2017 at 1:16am: Hello,

I am encountering a problem with the optimize cross section.

I just download example file from http://www.karamba3d.com/examples/hard/large-deformation-of-a-shell/, but there is an error when I open it, like"151 cross sections need to be bigger than their biggest family member", so what should i do to correct it? .....I am new...

Thank you

Comment by Matthew Tam on May 8, 2017 at 12:43am: Hi Earth, if you wish to run multiple analyses automatically, you can look at either optimisation processes such as Galapagos or Octopus or you can simply use a Data Recorder to record your results.

Best,

Matthew

Comment by Earth on May 6, 2017 at 5:28pm: Hi all, is it possible to run 100 karamba analysis automatically using different values of variables? and record the results? Thank you.

Comment by Karamba3D on April 8, 2017 at 4:36am: Hi Martin,

you could use short connector beams with corresponding joint definitions at their ends.

Please open a new discussion if you want to discuss the matter further. The comment wall is not so well suited for that.

Best,

Clemens

Comment by Martin Engdahl on April 4, 2017 at 12:09pm: Hi!

I just downloaded Karamba trial about an hour ago, and I cant get going with my model. I have an interlocking structure (eggcrated, see picture: there is an error in that the long beams should rest on the arcs, not the other way around as it is now) that is to be glued together. How would I set up an analysis like this?
