Finite Element Analysis (FEA)
Computational technique for analyzing physical systems by dividing complex structures into simple elements, solving their individual behaviors, and assembling results into complete solutions. Applies mathematical differential equations to predict stress, strain, thermal, and other properties.
Why it matters
FEA is the mathematical foundation for all modern simulation, predicting everything from nuclear explosions to aerodynamic performance. It enables product design and optimization without physical prototypes.
