  • You could say the same for a finite element model. A junior engineer with just 4 years of training can solve, explicitly, the deflection at the center of a slender, simple-simple beam of prismatic section and produce an exact (if slightly incorrect) answer. Building a FEM of the same can solve the problem and take longer (to make the model) with similar accuracy, both of which are good enough for design work.

    Only a fool wouldn’t have a FEM around though, as it can solve problem that would take centuries for a human to solve. They may as well make a cartoon with the child digging a 3” hole in beach sand and then showing a backhoe making a jagged edged hole of the same size.










  • That’s sort of how I do mine. I put all my data onto dropbox/onedrive. I’ve got a $100 HP USFF hooked up in my office that is a 100% online mirror for those cloud accounts, and it backs up to an 8TB external each week. I rotate that drive with a spare each month (give or take), putting the “offline” one in a firesafe. It means I have a live copy (my pc), a cloud copy (OD/DB), a second hot copy (USFF PC), a near-line backup no more than 7 days old that isn’t “live” and a cold storage copy that is no more than a month old (aka less than Apple’s deleted-pictures and Dropbox’s previous version storage time). It cost me two external drives and the mini-pc. And if all those fail I’ll probably be roaming the radioactive wasteland looking for food and losing that data won’t matter.

    Oh, and that little box also runs a small FTP server and my Torrents for my Linux distro collection.
