Hi Marco
I am working with concrete deck elements, specifically hollow-core slabs, and I want to model them accurately.
I noticed that in FEM-Design, there’s an option to convert a plate into its corresponding analytical plates:
This approach provides more accurate results for the moments in the deck elements:
But when I try to import the elements into GH I get an error:
My questions are:
-
How can I import my deck elements into Grasshopper if they are modeled with the analytical model set to “panel”?
-
Is there a way to create hollow-core deck elements in Grasshopper with the analytical model set to “panel”?
Thank you

Hi @AndreiM
Unfortunately, the plate with analytical set to panel are not fully develop as it was not demanded a lot.
-
As per the error, we do not currently deconstruct profiled plate with panels. What are you trying to achieve? It might be that I can share a little script that export what you need 
-
From the API, there is no current way to set the analytical model to “panel” and it is neither a quick task to implement 
However, from a FEA point of view, you can model the panels dividing the elements on your own. You will need to do some UV subdivision through Grasshopper but the solution is equivalent to what FEM-Design is doing behind the scene.
Btw, we will consider implementing the feature in more details next.

Hi Marco
I understand, well I guess then I will model the panels from GH, with the desired width so that should work. I was just wondering if there is a way around, but I can see that will be in the future.
There is no need to spend time on the script, as I was just curiouse about it. What happens if I change a plate to the analytical mdoel and then I wanna import that in GH. But I understand now.
Thank you
