Analyse shell with hollow edge beam

Grasshopper Karamba3D

Hi everyone,

I know solid inside a solid is not really what rhino likes.
But how would I analyze a hollow edge beam of a shell in Karamba?
The part in red is hollow, a pocket so to speak:

The shell has a variable heigth, which I am taking in account like this:

It is a bit unclear what you want to analyse from your screenshots. Do you have a a model that shows the structure you want to analyse?

Now i understand, i think there are two strategies you can use:

  1. simply split your original surface at the “hollow” part into 2, and apply a second material thickness - this is a simplified method2
  2. another is to model both surfaces and connect them with dummy elements as such Shells with two layer - Grasshopper / Karamba3D - McNeel Forum

Hi Matthew,

thanks for the answer!
Do I understand right?
Since I calculate the thickness from the shell projecting points on the mesh,I could substract the hollow distance from the material thickness in this parts?

Thanks and best,

Hi Baris, yes that is one method.

Thanks @matttam !
Maybe at some point it may get someone started, here is how I implemented Methode 1:
