No time to waddle through dozens of pages full of mathematics? Here’s how FEA works – the sticky note version! Basic math skills required.
Lagrange multipliers and their physical meaning
Lagrange multipliers are a handy way of adding constraints to an FEA problem. Be careful with them, though – or don’t trust your results.
Options for (numerical) torque computation
Knowing the torque of an electric motor is kinda important, so it makes sense to double-check your results by using an alternative computation method.
6 Things you might not know about finite element analysis
The title says it all. 6 things you might not know about finite element analysis, but should. A bit tongue-in-cheek, but still valid info.
SMEKlib update
The SMEKlib library (open-source FEA for electrical machines in Matlab) just received a huge update. Here’s a brief rundown, plus associated rambling.
Late 2017 Review
No matter what happened globally, on my personal level 2017 was a great year. Here’s a short rundown of the highlights, and what’s next.
Second-Order Finite Elements – Why, How, and When
You may have seen the term “second-order finite elements” mentioned once or twice. But what are they really, and where are they used? Read to learn.
Coarse meshes: Why and How
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.
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.
