Finite Element Analysis
A computational method for solving complex structural, thermal, and fluid problems by dividing into small elements.
Also: FEA · finite element method
Definition
Finite Element Analysis (FEA) is a numerical technique for solving complex engineering problems by dividing a continuous domain into a mesh of small, discrete elements and solving the governing equations for each element. The solutions are assembled to approximate the behavior of the entire system. FEA is used to predict stress distributions, heat transfer, fluid flow, and electromagnetic fields in structures and components too complex for analytical solutions.
Example
“Automotive engineers use FEA to simulate a car crash on a computer, analyzing how the body panels crumple and where forces transfer through the frame, optimizing crash safety without building thousands of physical prototypes.”
