Finite element analysis (FEA) is a computer simulation technique widely used by engineers to reduce the number of prototypes, experiments, and design-optimizing steps. FEA is the practical application of the finite element method (FEM) used for solving problems related to structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential.
The objective of FEA
In practice, FEA is used by design engineers during the product-development process as a tool for simulating how a product reacts to potential environment forces or conditions.
How does FEA work?
After importing or creating a geometry, the analysis can begin with breaking down the product's shape (basically a complex geometry with unknown structural behavior) into a finite element model that comprises a system of points, called “nodes”. Those points determine a finite number of simple linear or geometric elements (meshes) with a known structural behavior that subdivide the entire product shape.
The computer solves the necessary mathematical equations for determining the behavior of each and every subdivision of the analyzed product, then adds the results up to obtain the behavior of the entire geometrical structure. The results are displayed graphically using a post-processor and represent the computed stress, strains and displacement that occur in the finite element model when forces are applied.
FEA aids engineers to anticipate how the behavior of products is altered by physical effects like:
FEA is a tool for research and development used by companies for designing and optimizing products to gain a competitive edge against the competition in highly competitive markets. Over time, the usage of FEA software has expanded from larger companies and institutions to small business in many different industries. Naturally, there appeared many software dedicate solutions.
