Active magnetic bearings are widely used in high-speed machines and sensitive environments both. Here’s what they are, and how they work.
How FEA works – Post-it version
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.
