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.

Comment by qiushi on December 17, 2013 at 3:43am: Hi,

you mean I should install two karamba 32bit and 64bit, if I have both version of rhino in my computer?

Comment by Karamba3D on December 17, 2013 at 12:07am: Did you change the Karamba installation target directory to where grasshopper.dll resides? Did you install Karamba-64-bit for Rhino5-64bit and Karamba-32-bit for all other versions of Rhino? Did you have a look at http://www.grasshopper3d.com/group/karamba/forum/topics/karamba-use... and http://www.grasshopper3d.com/group/karamba/forum/topics/help-reques...?

Comment by qiushi on December 16, 2013 at 1:33pm: I have installed karamba1.04 for grasshopper 0.90064,why it doesn't show in grasshopper?

Comment by Karamba3D on November 20, 2013 at 12:00am: Hi,

use the 'Trapezoid-Profile'-component and set upper and lower width to equal values.

Comment by Matti Pirinen on November 19, 2013 at 2:35pm: Hi

im a bit comfused. (And not with my sexuality)

How can I create solid rectangular cross sections which are normal for wood and concrete structures?

Comment by Karamba3D on November 14, 2013 at 12:21pm: Hi Sofoklis, with the new versions of grasshopper (>0.9.0060 or so) and Karamba 1.0.4 you have to look up the installation folder of GH in Rhino (Tools/Options.../Plug-ins/Grasshopper - Properties). This is where Karamba 1.0.4 needs to be installed (and to where the installation path needs to be changed).

Sorry for the inconvenience. The issue will be solved in the next release of Karamba.

Best,

Clemens

Comment by SOFOKLIS on November 14, 2013 at 10:09am: Hi there! i had a problem installing karamba. I managed to install it eventually by installing it at "C:\Users\me\AppData\Roaming\Grasshopper\Libraries". I can see karamba now in grasshoper ,but i still canot use the assemble component. I instaalled karamba to other computers and it seems that when instaling it in the folder Program Files (x86)\Grasshopper for Rhino 5\ it seems to work completeley fine. The problem is whenever i instal grasshopper it never installs it on the "grasshopper for rhino 5" folder, so that folder does not exist. when i see the computers of some friends that location is the instalation folder for grasshopper. The thing is when i instal grasshopper there is no option to choose where it will be installed, so I dont know how to fix this. I have seen that others that had similar problems and tried to follow the instractions that where proposed, but nothing works still. Any ideas?

some impressions of my master thesis which is based on karamba.
karamba was a great help.

Comment by marco on October 21, 2013 at 12:20pm: Hi Clemens,

Thanks a lot for your reply. It's good to know that Octopus might be a better tool for multiple optimization. Once again - thank you for your help.

Best,

Marco

Comment by Karamba3D on October 21, 2013 at 10:19am: Hi Marco,

the necessity of weighting factors is the main shortcoming of single objective optimization algorithms in case you have more than one design target. There is no right or wrong - setting this factor is a matter of trial and error.

You could use e.g. Octopus which can do multi-objective optimization without the need of pre-set weighting factors.

Best,

Clemens
