Karamba

Hi everyone :)

I am new to grasshopper and even more so to Karamba. However, watching the tutorial and demonstration, as an architectural student I am very impressed and amazed at its capabilities.

While attempting the same structural analysis on the new parametric digrid structure that I have made, there was something that resulted in weird analysis results being displayed and hope someone can help with this. Thank you so much!

Apologies if it was some rookie mistakes but I hope to learn more about how the plugin functions and use it in my design!

Thank you everyone!

Hi Huang,

the scale of your model is probably not right (see attached file). Karamba interprets the input geometry allways as given in meters (or feet) irrespective of what you set in Rhino. In the above example the structure is roughly 314km large and the maximum deflection is 1.8E14 meters which means 1.8*10^14 meters.

Best,

Clemens

Thank you so much for the prompt reply :)

I have tried however to readjust the units into meters with the same results. the new c.Length is now ~519 m.

Thank you so much for your guidance!!

The default cross section for beam elements is a circular hollow cross section of 11cm diameter. For a structure of a height of 500m you have to define a proper cross section (see attached file). For this tower wind will be the governing load. You could generate it via the MeshLoad-component (see manual).

Best,

Clemens

Thank you so much for all the help. I didn't know the default dimensions initially. And yep, I would definitely try out the wind loading via Meshload! Slowly picking up the software bit by bit.

Cheers for the amazing plugin ^^
