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!
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!
Determining and Quantifying Sources of Uncertainty
Uncertainty quantification requires determining the sources of uncertainty, such as deviations in the product dimensions. Here’s how to do it.
Uncertainty Quantification Explained, and Why it’s Big Today
Uncertainty quantification is one of the biggest engineering topics of the last decade or so. Read to learn what it is, and why it’s important!
