Radio-controlled helicopters are cool. Even more cool are the electric motors in them, with their insane power densities. I interviewed a proud hobbyist.
Time-stepping versus time-harmonic analysis
Good afternoon people, I hope you had a great Juhannus. Don’t celebrate it? Start next year. It’s awesome. But to the point: I’ve written on several occasions about time-harmonic analysis, mainly in the context of finite elements (FEM). See for…
Reluctance networks 104: Practical implications
Welcome back to my post series about reluctance network analysis. I started it after the acceptance of my paper to the EPNC conference, after which we have discussed some typical mistakes, and seen what to do instead. Today’s post brings…
RN 103: Solving reluctance networks
Hi again, and welcome back to the fascinating world of reluctance networks! After last post‘s brief detour to the grim world of how-not-to, let’s get back to more positive matters. In other works, let’s see how solving reluctance networks happens…
Reluctance networks 102
Hello there, and welcome back to my post series about reluctance networks. They are kind an expertise of mine. However, they do not seem to be the expertise of quite many other researchers. Indeed, today’s post is about where almost…
Reluctance networks 101
Some months ago, I wrote about being busy writing papers both to the ICEM and EPNC conferences, the latter of which is being organized by our research group in Helsinki next month. Now, I’m happy to announce both were accepted…
Making time-stepping FEM faster, part 4
Hi folks! After a couple of serious and not-so-serious lifestyle-esque posts, it’s time to get back to work. Mine, to be exact. If you’ve read the previous instalments in this series, you know that I’m currently working on a faster…
Making time-stepping FEM faster, part 3
Hi you, and welcome the the third instalment in my blog series about my ongoing work! In the first post, I explained what time-stepping finite element analysis is and why it should be made faster in the first place. The…
Making time-stepping FEM faster, part 2
In my previous post, I outlined some basics of finite element analysis (FEM) in the context of electrical machines. I explained how the time-dependent behaviour is often analysed with a time-stepping algorithm or another. This approach typically requires solving hundreds…
Making time-stepping FEM faster
Hello folks, it’s been a while! First, there was Wappu (see here for some info) – kind of a big deal for tech students and alumni alike – after which I took a week-long holiday in my home region. Anyway,…
