Finite Element Analysis (FEA): 

FEA is a simulation tool that analyzes a model and helps predict how the model will react to any physical change such as force, tension vibrations, and heat. Additionally, it can as well simulate how different materials will affect the model. It simulates the action and produces the outcome in terms of mechanical properties such as stress and strain. It is extremely helpful when developing any modeled design to be able to do quick adjustments and improve the model instantly. In summary, FEA takes the model and creates a mesh. This mesh is a mathematical computerization the application develops that creates many small elements forming together into the shape of the model where the application will mathematically use the elements and produce results from the given boundary conditions. FEA will be used for many designing projects to confirm if safety requirements are met.
