Karamba3D

Karamba3D is a parametric structural engineering tool which provides accurate analysis of spatial trusses, frames and shells.

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.

Yes, there will be a Karamba3D version for Mac.

A quick question: Now that Rhino 6 WIP for Mac is released, will there be a Karamba Version for Mac ?

Thank you, best wishes,

Rudi

Dear Jhoseph=),

could you please add a new discussion on the topic below? The comment wall is not a good medium for technical discussions.

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.
