Finite Element Method (FEM) The finite element method (FEM) (sometimes referred to as finite element analysis) is a numerical technique for finding approximate solutions of partial differential equations (PDE) as well as of integral equations. The solution approach is based either on eliminating the differential equation completely (steady state problems), or rendering the PDE into an approximating system of ordinary differential equations, which are then numerically integrated using standard techniques such as Euler's method, Runge-Kutta, etc.

Introduction to Finite Element Method/Finite Element Analysis (FEM/FEA) The description of the laws of physics for space- and time-dependent problems are usually expressed in terms of partial differential equations (PDEs). For the vast majority of geometries and problems, these PDEs cannot be solved with analytical methods. Instead, an approximation of the equations can be constructed, typically based upon different types of discretizations. These discretization methods approximate the PDEs with numerical model equations, which can be solved using numerical methods. The solution to the numerical model equations are, in turn, an approximation of the real solution to the PDEs. The finite element method (FEM) is used to compute such approximations. August 22, 2017

FEM History Finite Element Analysis in 2016 is the most powerful computational tool for structural verification and analysis of multi-physic problems. It is widely used in different industries and engineering disciplines. From aeronautical, automotive, civil engineering, to heat transfer, fluid dynamics. 75 years ago, it was not so clear, 1940s, it was a time when first engineers started developing mesh discretization method and dealing with numerical approximations of the stress analysis. But that was also a time when the method was limited by lack of computers. It was 1960, when for the first time the term â€œfinite elementâ€ was coined in the article. In the 1960s the first FEM open source software was developed. 1965 brought NASTRAN â€“ NASA structural analysis solver tool. In 1967 Mr Zienkiewicz with his co-workers published the first book about FEM, â€œThe Finite Element Method: Its basis and fundamentalsâ€. 1969 was the year, when the Norwegian classification society â€“ DNV (Det Norske Veritas, today DNV GL) developed the first tool used in ships analysis â€“ Sesam. In 1980s started age of developing commercial FEA softwareâ€™s, pre- and post- processors became available and automatic meshing became a standard feature. Since then the method has been widely used for numerical modelling. During the last ten years two trends can be noticed. First one is that organizations focused on September 21, 2016
