How to approximately calculate behavior of solid element in Karamba3D

Hi guys, I’m new here. I’m working on my master thesis project which involves investigating optimal support. In my case, the supported object is not shell or beam designed but the volumetric sculpture under gravity. However, I saw an answer that karamba3d doesn’t have solid element but it can approximately calculate with existing elements. How could? Is it the way like changing edges of volumetric mesh to the beam?
