@Pierre_mplus you could use List.Insert with levels. Although it might require some use of flatten to get the desired output.
Alternatively, you could do some python coding to make the graph more compact.
Tried to create a small example, is it something like this what you’re looking for?
I tried insert, but i didn’t find the solution.
Here’s the example with simple lists.
My two lists has the same number of elements.
i want to add each element in each sublist and respect indices.
Thanks
With Create, Transpose and Flatten, you can combine your 3 lists into a new one.
I’m not sure that yours rooms and yours air flows will match in your first post.
Take the parameters values of the airs flows from the node Elements in Room.
