Nov 6, 2020 at 21:55 comment added user121926 I would gladly learn how to handle an open source FEA software that supports composite materials. I'm sure that I could build our workflow around a tweaked licensed free software if my boss let me do it. some times ago I started programming a little software to design sandwich stack-up structure loaded with simple bending stress. It's more educational than practical, and I did it especially for one of my colleague to understand composite failure criterions. I really love making tools like that but unfortunately I don't have enough time.
Nov 6, 2020 at 14:45 comment added user120894 I've supervised a couple of bachelor's dissertations involving FEA simulation of composite materials, so I'm aware that it can be a bit of a nightmare. But one could argue that, if you're using a proprietary FEA system that doesn't handle anisotropy and heterogeneity adequately, you really are stuck with that inadequacy, whereas if you're using an open source system, you at least have some chance of extending it to make it handle those things adequately.
Nov 6, 2020 at 14:18 comment added user121926 @DanielHatton Also, my role in the team is to take care of subjects that involves composite material structures. I don't know if you are familiar with it but not every FEA software implements well the use of composites. From my experience, most of the time you're stuck with basic things and your options are very limited. I will take a look at Elmer or FreeFEM++ though when I'll have more time. Thanks
Nov 6, 2020 at 14:05 comment added user121926 @DanielHatton Unfortunately I can't afford to be unemployed right now, but I am pretty confident about my ability to find a job, if not in what I aim, at least I can get something very similar to what I currently doing. I'm looking for a position more like "scientific programmer" than "pure mechanical engineer", something that involves more coding and less CAD manipulation. Honestly, I think there's a only a tiny chance that a game-changing error has crept inside our simulations because of software issues. It'll more probably come from human mistakes than anything else
Nov 6, 2020 at 12:32 comment added user120894 @Foussy While I agree with posters who've advised you to move on to a new employer as soon as reasonably practicable (then report this to an appropriate regulator, if your conscience hasn't forced you to do so earlier), one way to mitigate the risk of this "worst fear" in the meantime might be to verify your (and your colleagues'?) simulations using octave-bim, octave-fem-fenics, Elmer, or FreeFEM++. But it'll mean an awful lot of work for you, so it can only be a very short-term workaround.
