Finite Element Analysis (FEA)

Improve product design by simulating complex thermal, structural, and modal problems before prototyping.

What is FEA?

Finite element analysis (FEA) is the practical application of a mathematical method called finite element method (FEM). It is used to model complex structural and thermal problems. FEM is a way of subdividing complex geometry with unknown structural behavior into a finite number of simple geometric elements with known structural behavior, known as a FEM mesh. At the element boundaries, the displacements are equated with the neighboring elements and a matrix equation is developed. The equation is numerically solved and you can see the results graphically using a post-processor. The results displayed show you the computed stresses, strains, and displacement that occur in your model when forces are applied.

The computed FEA results allow you to optimize your designs by making changes and then easily re-running the various analyses. Incorporating simulation software early in the design process will help reduce the need for costly prototypes and late-stage design changes as well as improve product performance, longevity, and safety. FEA enables simulation and is especially useful for structural and thermal analysis, as well as modal, buckling, and dynamic analyses for both linear and non-linear problems. Basic simulation can and should be in the virtual toolkit of every engineer.
