I love using Matlab for FEM development. It’s easy to use, and it can be surprisingly fast if you know what you’re doing. Click to read my praise in detail.
Matlab Speed Optimization – Case Example 1
Here’s how to improve Matlab speed. Some general guidelines followed be more specialized tricks, and a case example. Couldn’t be much better.
Arkkio’s Method for Torque Computation
Arkkio’s method for torque computation of electrical machines is now available in Comsol. But what is Arkkio’s method, really? Read this and learn!
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…
Direction of a rectangle, part 2
Numerical orientation of a polygon continues Hi again! Last time, I wrote about how I was given some a very basic FEM mesh, and had to determine the magnetization direction of a permanent magnet from it. In simpler words, I…
Determining the direction of a rectangle
How to numerically determine the long axis of a polygon? This week, I tweeted some indecipherable-looking scripplings of mine. Although probably not apparent at first glance, I was dealing with computational geometry. Again. This time however, it was not point-in-polygon,…
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,…
