Finite element analysis (FEA) is the process of simulating the behavior of a curtain or assembly under given conditions so that it can be assessed using the finite element method (FEM). FEA is used by our engineers to help simulate physical phenomena and thereby reduce the need for physical prototypes, while allowing for the optimization of components as part of the design process of a project.

FEA uses mathematical models to understand and quantify the effects of real-world conditions on a part or assembly. These simulations, which are conducted via specialized software, allow engineers to locate potential problems in a design, including areas of tension and weak spots.  With the use of mathematics it is possible to understand and quantify structural or wave propagation, thermal transport and other phenomena.

Most of the processes can be described using partial differential equations (PDEs), but these complex equations need to be solved in order for parameters such as stress and strain rates to be estimated. FEA allows for an approximate solution to these problems.  FEA is the basis of modern software simulation software, with the results usually shown on a computer-generated color scale.
