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.

Hi, Karamba,

I purchased a student license a few hours ago, I'm aware that it might take 2 days for you to handle the process, but I have an assignment due next Monday, can you help me accelerate my request please? I'm really in a hurry.

The machine ID and payment credential were send to info@karamba3d.com.

Thank you so much!

Hi Vincent, it should not make a difference. Simply send us the machine-id file as is and if you encounter any issues, just email us.

best,

Matthew

Hi Niklas,

as this relates to an Octopus issue, you should post this query on the Octopus forums. Unfortunately we are unable to help with this specific issue.

Best,

Matthew

Hey there, 
I am trying to get familiar with the cross section optimization of bridges, but when I want to open the example from the Karamba website I got an error: 

Component Octopus {f0913905-0d71-4c22-b63d-60d6e6cf4cf6} failed to deserialize itself: Die Datei oder Assembly "HelixToolkit.Wpf, Version=2013.1.10.1, Culture=neutral, PublicKeyToken=52aa3500039caf0d" oder eine Abhängigkeit davon wurde nicht gefunden. Das System kann die angegebene Datei nicht finden.

What am I doing wrong?
Did I open it with the wrong version of Octupus?

Thanks a lot, 

Niklas

Hi Kudrah,

i see that you are working with millimeters in your file. One thing is that Karamba interprets all units in meters. Therefore if you input geometry that is in your model 4000mm, it will interpret this as 4000m. This can be one issue causing the load densities. You can also increase the Length Segments slider in the Render Settings tab of the Model View to reduce the number of visible loads in the Model View.

best, Matthew

Hello,

i seem to have a problem with my beam view not working and i just cant seem to understand why. Your help will be much appreciated. Also is there a way of how i can reduce the number of the yellow lines representing the mesh load so that they don't seem so dense for visual appeal? Basically, i need to reduce them and space them and possibly increase the arrow size showing the direction of the mesh load.

Thank you

Dear Jhoseph,

In these situations I usually generate loadcases for each type of Load, as Karamba analysis is linear is not a problem to magnify the design loads after the analysis.

To test diverse load combinations I generate scripts that take the caractheristic values from the analysis and returns all the design combinations. My undergraduation thesis is the creations of plugins that apply Eurocode 5 for verification of timber structures and i'm using this a lot, please fell free to contact me for further explanation.

Cheers.

Hello Karamba team!!!

How could I perform the following load combinations in karamba?

Thank you! 

Comment by karamba on June 3, 2018 at 11:51pm

Dear Leonie,

the problem in your definition with multiple voxels is, that you provide one mapping only. This means that all upper and lower voxel boundaries are handled like one upper or lower girder of a truss. Due to this there are voxels with no connections at all (see attached definition 180531_stitchedsystem_multipleVoxels_LE_CP.gh) which cause rigid body modes. In order to solve the problem reduce its complexity and start with two voxels only.

Please open a new discussion on the subject since it is easier to follow and find for others as compared to a comment on the comment wall.

Best,

Clemens

Dear Karamba Team, 

I have a question concerning a Problem in my studies with Karamba.

I have a "voxel system" (Bounding boxes for a later on Geometry)(01_Image). I took the upper and lower edge curves from the the boxes to apply in between some optimized diagonals(optimization of the position of the points on the lines) for that I am using the Idea of Element Felting and the mapper component(+ the different stich possibilities). For one Box(02_Image) it works totally fine but by applying it on all my voxels it does not work how I imagine. So the aim for me is that every box has its own diagonals. Concerning the set up I just set up a fast Karamba model the supports and the loads will be than later on in a more detailed way defined. 

Could someone help me applying the system on all voxels ?

Thank you!

All the Best,

Leonie 

I uploaded two scripts the one for one voxel where the system works and the "multiple Voxels" scripts where it doesnt work.

The Images should show the one voxel and the Idea and the other image the basic voxel massing.
