When analyzing electrical machines, a course, parametric mesh often outperforms a denser mesh. Here’s why, and some progress updates on the topic.
Magnetomechanical Coupling – Physics and FEA Models
The magnetic forces in an electrical machine deform it, and the mechanical stresses influence the magnetics. Read more about this interaction here.
Of Intelligence, and Arrogance
You are not the smartest person in the room. No-one is. Hi folks! Just a short post this time: I had a rare moment of inspiration (usually writing’s just manual labor instead), and I want to make the most of…
Electric Aircraft
Alright, everyone’s seen electric cars. But what about electric aircraft? Who’s making them, and more importantly: why? Some challenges and benefits here.
Machine Industry Sucks at Recruiting
How to recruit electrical engineers, or any other professionals in short supply. And how almost everybody is failing at that.
Of Learning and Luck
Learning kinda follows the Pareto principle, and kinda doesn’t. Additionally, by sheer non-luck, you often do need the stuff you happen to learn.
Circuit Connections – Why You (often) Shouldn’t Use Current Supply
Current supply is commonly used in finite element analysis of electrical machines. Almost as commonly, that’s the wrong solution.
Winding Losses – If and When They Matter
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.
