Start sim at 8pm (ie, when nobody else is using the shared compute resources) --> jack off for 7 hours while occasionally checking that the sim hasn't crashed --> check my results when sim finishes at 3am
A hard day's work in the life of a simulation engineer
Yeah... I made the mistake of looking for more work early in that job and got the dead time filled up pretty quickly. I quit that job and I'm a grad student now, but they probably are still hiring. It was an airforce engineering contractor job in Florida, so it's not very hard but it's an employees market due to strict degree/nationality hiring requirements and general unpleasantness of living in Florida
