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.

Karamba3D Joint Error 5 Replies

Hello. I’m trying to make scissor structure on grasshopper using karamba. When I want to define joints in assembly, it gives me an error. How can I define connection of the elements with revolute…Continue

Comment by pyrit on May 3, 2012 at 2:35am: hey

i did dl the latest version of karamba @ your old site, so that was outdated . with new version by http://www.karamba3d.com/ it works

thanx

Comment by pyrit on May 3, 2012 at 2:03am: hi @ll,

i have some probs with opening the example files.

e.g for LargeDeformationFormFinding_1.gh

maybbe you could ubdate - big thanks !

Comment by David Shook on March 16, 2012 at 12:04am: 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.

Comment by David Shook on March 16, 2012 at 12:04am: 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.

Comment by Parametric House on November 11, 2011 at 10:23am: 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 :)

Comment by Karamba3D on November 6, 2011 at 11:33am: I-sections should appear as I-sections, Boxes as boxes,...

Please post your definition in case karamba behaves differently.

Best, Clemens

Comment by sivam krish on November 4, 2011 at 8:22am: 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?
