I'm currently trying to grok the finite element method. Gilbert Strang's explanation of the transition from the Galerkin method to FEM did more for me in terms of connecting the dots than anything else I could find on the web. And it wasn't even a lecture, just a kind of an interview. I think it's this one: youtube.com/watch?v=WwgrAH-IMOk

But I think that might be because you've seen the equations dozens of times, and I haven't seen them at all, so you were prepared to understand the video.
- praptak 6y agoThis makes sense. As said, it was about connecting the dots for me. Also, I don't even claim I fully understand FEM (or even Galerkin), it's just my hobby project.
- kragen 6y agoThat sounds interesting! What are you doing with it?
- praptak 6y agoI just want to understand the magic behind static stress analysis. More generally I'm interested in emulating physics behind the rigid body model. Maybe I will create a game prototype based on the mechanics but this is just a vague idea.
