main features - with those of the pro-version in blue:

available as 32- and 64-bit application
fast topoligical manipulation of models: stitching and felting with beams
fast linear interpolation between the geometry of multiple models
enhanced model handling capabilities as compared to version 0.9.083
calculation of large deflections (for form-finding) and small deflections of beam and truss structures
display of strains, stresses, utilization and section forces/moments
arbitrarily oriented supports, display of support reactions
circular tubes, I-sections, box-sections, trapezoid-sections of variable shape
springs between nodes
hinges at the endpoints of beams
eccentricities of beams with respect to the line connecting their end-points
cross section library for steel sections
variable material properties, material library
nodal forces, equivalent nodal forces from distributed forces on meshes, gravity, uniformly distributed line-loads, axial pretension
multiple load cases
predefined displacements at supports
calculation of eigen-modes of the structure
determination of natural vibration modes and frequencies, consistent mass, user-defined point masses
ForceFlowFinder that provides all the functionality previously contained in the ESO/BESO-components plus some extra features
cross section optimization
retrieval of results
- normal force and resultant moment per element
- section forces, moments and displcements at arbitrary positions along elements
- utilization of elements
- reaction forces and moments
- internal bending- and axial deformation energy per element
- nodal displacements: translations and rotations
- displacements along elements
- approximation of principal strain fields on grid shells for force flow lines

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i did dl the latest version of karamba @ your old site, so that was outdated .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 Mohammad Yazdi 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 karamba 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 karamba 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?
