Hey,
I'm analyzing an anti-roll bar for a car. Essentially there is a lever arm on both sides of a long tube, and then an opposite direction force is applied to each lever arm, causing the bar to twist. Since I am using block elements, I know that the nodes don't actually rotate, but translate instead. What I'd like to find out, is the degree of rotation of the bar. Looking around, it seems like I need to use beam elements, but I couldn't find much about applying those to block elements, namely at the center of the bar going its length. I tried to do it but seemed to fail catastrophically. Anyone have tips for adding a beam element to a hollow tube and analyze its rotation?
Thanks for your help.
