Finite Element Analysis, commonly called FEA, is a method of numerical
analysis. FEA is used for solving problems in many engineering disciplines
such as machine design, acoustics,electromagnetism, soil mechanics, fluid
dynamics, and many others.
In mathematical terms,FEA is a numerical technique used for solving field problems described by a set of partial differential equations.
In mechanical engineering, FEA is widely used for solving structural,
vibration, and thermal problems. However, FEA is not the only available tool
of numerical analysis. Other numerical methods include the Finite Difference
Method, the Boundary Element Method, and the Finite Volumes Method to
mention just a few.
However, due to its versatility and high numerical efficiency, FEA has come to dominate the engineering analysis software market, while other methods have been relegated to niche applications. When implemented into modern commercial software, both FEA theory and numerical problem formulation become completely transparent to users.
