hello!

I have aB question about utilization. As shown in this image, utilization of element sometimes comes to be 2001.19 ( to be exact, utilization/100), in spite of not so big stress. Could somebody tell me the reason for this?

hello matt,

i have changed the surface and tried to run the analysis on it to get the stress lines. The output is very much pleasing however i wanted to verify whether the methodology is correct or not ?The support conditions are where the surface meets the ground and the load is gravitational

thank you.

Hi Ishan,

your geometry is still not symmetrical in three directions, also the input points for the shell lines need to be also symmetrical.

Hello Karamba, I need to optimize sections of steel truss with the norm AISC 360-10 standard, Karamba optimiza with the Eurocode-1993, was reviewing the hacker guide and I need to see the operation of the "optimize cross section" component, but I can not find the file karamba.dll, Where i can find it? , I have the version of Karamba 1.3.0 for Rhinoceros 6. Thanks!

hello matt,

i have re made the surface with equal point distribution..but still the stress line distribution is not that equal...can you have a look once.

thank you

Hello,

I'm new to Grasshopper and Karamba. I have created a simple scissor stucture in Grasshopper and wanted to do a structural analysis using Karamba. I am working on my PhD thesis. The model which is in attachment shows double joints at the end of scissor elements, because there are two of coincident points /the end of one beam is the start of another one/.

I do not know the way to fix this.

Could anyone help me with this, please?

Hi Ishan,

at first glance, it seems that you used random points to draw the shell lines. Did you try inputting points that are exactly equally distributed in all three directions on the surface to see if the line outputs are equal?

best,
Matt

Hello,

I am trying to create stress lines on a modified enneper surface,

however the stress lines are not being equally distributed, the support are taken at 3 points where the surface is meeting the ground...i have already given the points in the grasshopper file...

i hope i can get equal distribution of stress lines...

thank you, ishan

Hi Joe,

you can start by first creating your geometry in Grasshopper or manually drawing it in Rhino. Afterwards you can follow the Parametric Truss of Buckling Bridge example on our website to guide you how you can set up your line geometry as beam elements to bring it in Karamba.

best,

Matthew

Hello, 

I am a complete nube here and want to know how to analyze a space frame using karamba unfortunately I don't even know where to begin and the videos are not much help to me. If someone could lead me in the right direction that would be great. Like I said I am a beginner and have never worked with the program before so any help I can get would be great.
