Finite element analysis (FEA) is a computational method for predicting how structures behave under loading, vibration, heat, and other physical effects. This technique allows entire designs to be constructed, evaluated, refined, and optimized before being manufactured. Finite Element Analysis, or FEA, is the process at the core of mechanical engineering and one of the key principles for simulation realm.

It follows on from matrix methods and finite difference methods of analysis, which had been developed and used long before this time.

If two engineering systems can be formulated as a mathematic model with the same set of differential equations;

Finite Element Analysis Finite element analysis (FEA) is a generic approach to solve differential equations subjected to BCs.

Finite element analysis, utilising the finite element method (FEM), is a product of the digital age, coming to the fore with the advent of digital computers in the 1950s.
