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.

How to define 3D Objects in Karamba 6 Replies

Hello. I have a problem in defining 3D Objects in Karamba. What I am trying to do, is that I have 3D scanned a few Irregular stones. So I have their 3D meshes in grasshopper. Then I am trying to…Continue

Response from Karamba:

Karamba works on Rhino 32bit. It doesn’t do so for the 64bit-Version because the calculation core is a 32-bit-dll.

The next version of Karamba will work on 32 and 64-bit machines.

I am using Karamba for structural analysis and optimization.  I've  been moving my GH components over to Rhino 5 and I'm having trouble with the Analysis component.  Here are the steps I've gone through (3 times now).

1. Install latest Rhino 5 beta 64-bit.  Keep old Rhino 4 install.
2. Copy over GH component files from Rhino 4 since you cannot specify the install directory when installing GH.  Add GH as a plug in for Rhino 5.
3. Install Karamba Free 0.9.083 to Rhino 4.  I tried to install Karamba to Rhino 5 beta (under C:\Program Files\Rhinoceros 5.0 Beta (64-bit)\Plug-ins\Grasshopper\Components) but when I install no files appear in the directory.
4. Copy all Karamba files to Rhino 5 directory.

5.  Start Rhino 5 and GH.  Karamba appears in the toolbar and everything appears fine, but I receive the below error from the Analysis component:

Error: Solution exception: The type initializer for 'fem.karambaPINVOKE' threw an exception.

Absolutely great piece of work. I combined it with galapagos and it solved my problem in minutes! That was a 2 day work to export to Sap2000. Thanks for your beautiful work :)

I-sections should appear as I-sections, Boxes as boxes,...

Please post your definition in case karamba behaves differently.

Best, Clemens

Is there a plan to make the sectional profiles visible ? currently they all appear to be tubes ?

Comment by Karamba3D on November 2, 2011 at 2:56pm

Hello Najna,

you can use the MeshLoad-component to automatically generate point-loads from distributed loads.

Comment by Najna Sorin on November 1, 2011 at 4:47am

I love the new version, too.

I am especially interested in the feature: "Free-form structure under uniformly distributed loads - optimized cross sections and bending moments:" shown on the last image above. Is this a new feature?
How to automatically apply that uniform load to a free form structure?

Comment by David Shook on October 31, 2011 at 2:30pm

Remarkable new version, very exciting developments.  Keep up the good work!

Comment by madmax on October 16, 2011 at 8:58am

hey guys!

i want to try karamba example out of the manual, but analyze component turns red...

do you have any ideas where the problem is?

it would be nice if you could help me!

Comment by Karamba3D on October 13, 2011 at 12:58pm

Beams with bending switched off transmit normal force only. A node that connects to such elements has three degrees of freedom. In case of a planar truss add out of plane supports at all nodes (see also subsection 'Bending stiffness' of section 'How to change beam properties' in the karamba manual).
