No need to imagine this:

We have operated a Linux cluster for nearly 5 years now that Hydro (the
Aluminium company) uses to simulate the energy transfer/structure
deformation that happens when a (sports) car using one of their
aluminium frames with integrated "crash box" structures get into an
accident.

Yes, it is a _lot_ cheaper than running real crash tests, even though
you still have to verify the theoretical results before the car will be
certified for road use.
