In the case of FEA, these laws consist of different conservation laws, laws of classical mechanics, and laws of electromagnetism. The foundation of FEA software is formed by the laws of physics expressed in mathematical models. Over time, the use of FEA software has expanded from larger companies and institutions that support educating engineers to smaller companies in many different industries and institutions with a wide variety of disciplines. Therefore, FEA is an integral tool for research and development departments in companies and institutions that operate in highly competitive markets. This has sparked new ideas and completely new designs and operation schemes that would have been hidden or otherwise impossible without modeling. The introduction of high-fidelity models have also contributed to an accelerated understanding. Optimization methods are usually included in the solution process, which is further described in detail below. Most modern FEA software features methods for describing automatic control and incorporating such descriptions in mathematical and numerical models. At this stage, optimization methods and automatic control may provide the last degree of improvements that can be difficult to obtain with intuition only. Once an FEA model is established and has been found useful in predicting real-life properties, it may generate the understanding and intuition to significantly improve a design and operation of a device or process. For this reason, it may be reasonable to increase research and development resources for FEA. They do, however, get more development for their dollar, which may result in gaining a competitive edge against the competition. This does not necessarily mean that companies and research institutes save money by adopting FEA. The purpose of finite element analysis (FEA) software is to reduce the number of prototypes and experiments that have to be run when designing, optimizing, or controlling a device or process.
