karamba replied to Lukas G's discussion Intersectiom Joints in the group Karamba
"Hi Lukas, you could use short springs to connect the beams of the different layers: choose the translational stiffness very large to come close to a rigid connection, select small values for the bending stiffness (e.g. 0.1 kNm/rad). Best, Clemens"

karamba replied to Kendrick Tay's discussion Glulam Simulation in the group Karamba
"Hi Kendrick, at the moment (version 1.2.2) there is this limitation for the transverse shear stiffness you mention. In version 1.3.0 this limitation will be lifted. The shear stiffness influences the results only in case of very compact…"

karamba replied to Balazs Kisfali's discussion Angular steel cross sections to cross section table in the group Karamba
"Hi Balazs, you can use the principal values of the moment of inertia of the cross sections to specify them. In Karamba the calculation will not be exact in case of loads which produce shear, since currently (version 1.2.2) Karamba assumes that the…"

karamba replied to Simon Clavelin's discussion Conversion from principal stress/force to global coordinates in the group Karamba
"Hi Simon, in version 1.2.2. it is not possible to adjust the coordinate system of shells and thus the direction in which the shell cross section forces are output. This will be a feature of Karamba 1.3.0. Best, Clemens"

karamba replied to shabnam lotfian's discussion arbitary cross section in the group Karamba
"Hi Shabnam, at the moment (version 1.2.2) Karamb can only handle beams with constant cross section. As a workaround for variable cross sections you could split the beam axes into small segments and then give each segment a different cross…"

karamba replied to Simon Clavelin's discussion Mesh loads: point load generation and meshing issues in the group Karamba
"Hi Simon, the structural response of shells is dependent on the mesh refinement. ad 1.) It is hard to say why the GH mesher gives different results for identically shapes surfaces - maybe the order of the boundary lines is different. ad 2.) In order…"

Matthew Tam commented on karamba's group Karamba
"Hi Earth, if you wish to run multiple analyses automatically, you can look at either optimisation processes such as Galapagos or Octopus or you can simply use a Data Recorder to record your results. Best, Matthew"

Music Pavilion - Salzburg Biennale 2011

The primary design intent for the art pavilion was to create a recognizable presence for contemporary productions in Salzburg, a city that is predominantly known for classical music. The main user of the pavilion is the Salzburg Biennale, a festival for contemporary music.

A 2-meter long aluminum profile is arrayed to create oscillating spatial effects. The single sticks merge into a mass-like structure that changes its appearance during the day according to different light conditions.…

Can someone help me with the definition of karamba cross range selctor connected to galapagos?!?!?!

Hi,

Thanks for the reply.It was  an attempt to see how far can I go with the form finding using karamba for my master thesis .I was trying to simulate core material.I discovered It is not realistic to do this in grasshopper since that needs professional fem software "3d meshes ".I am now using Autodesk robot to simulate different iteration of the model to prove it works first.Then I will look if it is that important to use the interface between grasshopper and the fem software.I would appreciate any advice from you.I am also looking for buckling analysis to evaluate modes to refine my design for modal displacement and deflection later on.

Hi,

I am trying to get an inner structure for a shell design that I am designing.I have tried this simple unite using the shell element in Karamba but the results are far beyond expectation.My reference was the waffle gh file in the examples.for the inner structure.The meshes are fine the first image shows the millipede solver result.So the problem is not a mesh problem and not a material problem because I tweaked the materials with no improved results.is it a shell element problem that I don't know ?? 

The backed image shows the inner walls without the outer ones although the outer ones are included in the calculation.

Hi Karamba,
I know that all of you are quite busy and trying to help users as much as you can.
As was just wondering if you could take a look at thistopic related to buckling of members in Karamba. Robert started replying but, he might be busy until the end of the week.
So if you have some tiny amount of spare time, I would be very grateful.

Danke.

I understood the FFFcomponent as a tool to eliminate the less used beams.

the TCE defines the most usage in compression <OR> tension. i think i need both criteria.

+ there is the old problem of leafing single beams, what doesn´t look useful at all.

-however I just wanted to redefine our work of the workshop - i wasn´t able to craete the same structure -yet !
