FiniteElementAnalysen

Finite-Element-Analysen, often abbreviated as FEA, is a numerical method used for solving complex engineering and mathematical problems. It is particularly effective for analyzing the behavior of physical systems under various conditions, such as stress, strain, heat transfer, fluid flow, and electromagnetic fields. The core principle of FEA involves discretizing a continuous physical domain into a finite number of smaller, simpler subdomains called finite elements.

These elements are typically connected at specific points known as nodes. Within each element, the governing physical equations are approximated using simpler functions, often polynomials. By assembling the equations for all individual elements, a large system of algebraic equations is created, representing the behavior of the entire domain. This system is then solved numerically using computers to obtain approximate values for the physical quantities at the nodes. The accuracy of the FEA solution depends on factors such as the element type, mesh density, and the order of approximation functions used. FEA finds widespread application in industries like automotive, aerospace, civil engineering, and biomedical engineering for design, simulation, and optimization purposes.
