If your legs have solid-cores then, given your dimensions, it would be best to analyze these with solid elements. If they are not solid-cores what is wall thickness of your legs?
Thanks for the quick reply. Currently me and my mates are building our grasshopper model, to do a parametric study, that is why we can’t yet give proper dimensions. I am guessing it is will be around 40cm high and 15-20cm thick. The legs will be solid concrete.
Is there a way to use solid elements for them, as from what I am reading in the manual, the FEA build into karamba is programmed to have only shells.
However now I am thinking if the elements that we have made in Rhino are solids is karamba going to take them as solids after meshing them?
I have attached a photo of how the model is supposed to look like, however the dimensions are not final because we don’t have a full grasshopper model build yet.
I can't speak to the capabilities of Rhino or Karamba but in SOLIDWORKS Simulation such a model would be analyzed using solid (tetrahedral) elements. Shell elements in SOLIDWORKS Simulation are for analyzing thin walled objects or thin plates. From your image and description it seems that your design is neither of these so solid elements would be required.
