# Finite Element Analysis (FEA)

FEA – Finite Element Analysis is a computerized method to predict response of a product to the given load or testing conditions such as real-world forces, vibration, heat, fluid flow, and other physical effects. FEA Simulation helps to reduce the number of physical prototypes and experiments and optimize components in their design phase to develop better products, faster while saving on expenses.

FEA was developed originally for numerical solutions of complex problems in solid mechanics. FEA helps engineers to find weak spots, areas of tension, etc. in their designs. Finite element analysis shows whether a product will break, wear out, or work the way it was designed/process changes in very early stage, and then save project redesign/testing time, cost, etc. The working principle of FEA is to subdivides a large system into smaller, simpler parts that are called finite elements. This is achieved by a particular space discretization in the space dimensions, which is implemented by the construction of a mesh of the object: the numerical domain for the solution, which has a finite number of points. The finite element method formulation of a boundary value problem finally results in a system of algebraic equations. The method approximates the unknown function over the domain. The simple equations that model these finite elements are then assembled into a larger system of equations that models the entire problem.

The result of FEA only gives an approximate solution to the problem. It is a numerical method to predict how a part or assembly behaves under given conditions. The results of a simulation-based on the FEA method are usually depicted via a color scale that shows, for example, the pressure distribution over the object. Inputs we need to run FEA simulation are 3D CAD model, or 2D drawings with all dimension information, detailed load conditions and material property for each components. FEA is by far the most widely used and versatile technique for simulating deformable solids. Little P.Eng.
