When talking about engineering simulations, it is common to come across the terms FEM and FEA. Although they are often used interchangeably, there is an important difference between them.
Differences between FEM and FEA
What is FEM?
The Finite Element Method (FEM) is a mathematical technique used to solve physics and engineering problems. It is based on dividing a complex object into small parts called finite elements, making it easier to analyse its behaviour under different conditions. It is a fundamental tool for studying structures, fluid dynamics, heat transfer and more.
What is FEA?
Finite Element Analysis (FEA) is the practical application of FEM. It is the process of modelling and simulation using specialised software to predict how a design will respond in the real world. FEA allows materials, geometries and conditions to be tested before manufacturing, reducing costs and risks.
Differences between them
- FEM is the mathematical method.
- FEA is the application of that method in a specific analysis.
In other words, FEA uses FEM to solve real problems. If you think of a recipe, FEM would be the theory of cooking and FEA would be cooking a dish by applying that theory. In the world of engineering, this translates into structural simulations, strength tests and design validations.
