We recently ran into a situation where we got an update to NX and the new version physically couldnt model a part we had designed. The part was very specifically designed around its aero features. Our CFD PhD said itd take him 3 months to determine the impact to the features.
I sat down with one of the other engineers, we ran through every scenario possible, ran it all through 1d flow solver models, and determined worst case scenario (which we were certain wasnt going to happen) was 7 degree F change to the metal temperature. When we’re talking metal temps 1200F+, 7 is insignificant.
We came to that conclusion in 4 hours and told the team to keep going with what NX could do.
Bingo. It’s like this here too.

I dunno what any of that means but that’s cool. I thought aerospace engineering would be working with metric units even in the USA though.
All my schooling was is metric units, but my 15 year career in the USA has all been standard units
