When should you invest time and money into computing additional winding losses in a machine?. And when is simply winging it enough?
The 4+1 Types of Convergence
Engineers and mathematicians both love to speak about convergence, often confusing the everloving waste out of each other. Read here to avoid that fate.
Solving TEAM30a with SMEKlib and Comsol
How to solve the TEAM Workshop Problem 30a with SMEKlib, plus a comparison between it and Comsol. This time, SMEKlib was 5 times faster.
Business coaching
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!
