Finite element analysis (FEA) is a simulation tool that divides complex structures into smaller elements and uses mathematics to predict how the structure will behave. FEA is used across industries to optimize designs, reduce costs, and minimize risk by validating virtual models with physical testing. The FEA process involves building a CAD model, generating a mesh, applying loads and properties, and analyzing the results to improve performance.
