Topology-optimized beam
The classic cantilever: a box design space, the left face held, a downward load at the tip.
Topology optimization keeps at most 40 % of the box's volume, placed where it carries the load best, and the result is smoothed into a solid you can keep modeling with. The optimization runs in the browser.
