What is finite element?

Finite element analysis (FEA) is a numerical technique used to solve complex engineering and mathematical problems. It works by dividing a structure or domain into smaller, simpler parts called finite elements. These elements are interconnected at nodes, and mathematical equations are applied to each element to approximate the behavior of the whole system. FEA is commonly used for stress analysis, heat transfer analysis, fluid dynamics, and electromagnetic simulations, helping engineers predict how a design will perform under various conditions.
