Hi Marinella,

There seems to be something wrong with your images...

Best regards,

Hi Filipe,
if it’s better I can attach my rhino file with the portion of shell.

Thanks a lot,
Marinella

Hi Marinella,

What I mean is that when I click the images on the links these are appear clipped. I'm not sure I can help, but I'll try. Yes, either upload the rhino file or the re-upload the images.

Hi Filipe,

I think I sort it out. Let me know.

Thanks a lot.

I would suggest trying to follow a tutorial first on how to model shells in karamba, if your question is on how to do it. I would say you need to model each one of the pieces of your dome as a mesh. You can simulate multiple meshes connected with each other, which I think is what you want. I believe that karamba models the shell-to-shell interfaces as glued, which may be what you are doing or not. I added a quick example

Hi Filipe,
thanks for your anwer.
I think to model each piece as mesh is a good solution, but what about the connection system? I have this puzzle-like connections that I want to insert in my simulation, how can I define them in Karamba?

Thanks again,
Marinella

Aren't your connections integral? Or in other words, aren't the connections part of the piece geometry? Just model each piece as a mesh, a planar face with the piece geometry. Though, one important problem you'll face is planarity issues with the connections. To correctly simulate the behaviour of your structure you would probably need to use solid meshes. You will have to check with the Karamba team (Clemens for instance) if this is possible in Karamba.

On a side note you need to look at Pedro Varela work on stereotomy. If your vault is a compression only structure you don't need the connections.

Hi, 

the connections are part of the structure, my vault should work on compression but I created the connection system, not for structural purposes, but more to assemble the structure. 

The pieces are planar and the connection help to connect the different orientation of the pieces as well. 

This is the file just to give you an idea. 

And yes, I'll check his work out.

Thanks a lot.
