Want to see some first-rate BS? Google ‘business coaching’ and see what somes up. There are some gems, of course, but they’re hidden DEEP.
Periodicity, Symmetry Sectors, and Associated Errors
Electrical machines are often simulated with symmetry sectors and periodicity conditions. This speeds up things a lot, but occasionally leads to weirdness.
Thesis Language Check Done
Per university rules, I was obligated to have a language check done on my doctoral thesis. Here’s how it went, and how you can buy a beer for me.
Lessons from Teaching, and More
You learn the best by teaching. Here’s what I learned by lecturing a Master’s course called Numerical Methods in Electromechanics.
Fixing a 100-Year Old Mistake with SMEKlib
You’ve seen the textbook example of skin effect in rectangular slot-bound conductors. But what happens when the textbook is (slightly) wrong?
What are Skin and Proximity Effect, or Circulating Currents
Skin and proximity effect can dramatically increase the losses in your electromagnetic device, as can circulating currents. Read here to learn about them!
Egear and Quantum Electric – Motor News from Finland!
Two new electric motor inventions from Finland. In a way, both are aimed at increasing the operating range of the motor. Read here to learn more!
What is Karhunen-Lòeve Expansion?
Polynomial chaos can also be used to represent random functions, but for that purpose something called a Karhunen-Lòeve expansion is also needed.
Last Week’s FEA Tonight with Antti
Elsewhere in FEAsphere: failure modes, and how and why they are indeed uncertain. Plus stochastics in buckling, and some collaboration in the making.
Uncertainty and Maths – What is Polynomial Chaos
For analysing uncertain systems, something called polynomial chaos can be used. Despite the horrible name, it is actually quite simple. Read to learn!
