Finite Element Analysis (FEA) refers to the computer-based simulation technique used for predicting and analyzing the behavior of various physical systems, structures, and products. It makes use of complex mathematical algorithms to break down a complex design into smaller, more manageable parts, which can be easily analyzed. There are several synonyms for FEA, including Computer Aided Engineering (CAE), Computational Fluid Dynamics (CFD), and Virtual Simulation. Other terms used to describe FEA include Mathematical Modeling, Numerical Analysis, and Engineering Analysis, as well as Finite Element Method (FEM), which is the specific mathematical approach FEA employs. Despite the variations in language and terminology, all these concepts are closely related and often used interchangeably in the engineering and design industries.
