Thanks for the clarification! This makes sense. I do wonder who is liable if the software used to design a bridge outputs incorrect simulation results and the bridge collapses as a consequence. I suppose it's on the senior project engineer (or whoever ultimately signs off on the design) to verify the results somehow. Edit: This article [0] talks about the "trust" placed in commercial and open-source CAD software by engineers and doesn't mention regulation/certification of the software itself, which seems to imply that there is none.
