Did you ever experience any times when a part passed the math model, but didn't "look right"?

- WalterBright 7y agoSort of. I spent much time arguing with Stress over how to calculate the torsional rigidity of the elevator structure.
- WalterBright 7y agoI don't mean to be too hard on Stress. They're good guys, we both had the best interests of the design at heart. Their manager paid me a great compliment by wanting me to join their team. But I liked design work too much.
- Scramblejams 7y agoBTW, this happens all the time when using structural optimization programs, where you tell the computer what material you're using, how it's constrained and loaded, and then it figures out what it thinks is the optimal shape for the part. It means somebody left out a load or a constraint, or messed up the material properties, which is all another way of saying the math model is wrong. So when a part doesn't look right but seems to pass the math, be very suspicious of the math! :-)
