FEM is a common powerful numerical method for solution of partial differential equations in applications which need to capture local effects. For a given design, the

It is assumed that the reader has a basic familiarity with the theory of the nite element method, solution. The ﬁnite element method (FEM) is an extensively used numerical method. The method was ﬁrst proposed in 1940s and applied ﬁrstly by Courant, a mathematician, to solve torsion problem. The FEM was mainly used in mechanical and structural ﬁelds.

The method started with promise in the modeling of several mechanical applications in the aerospace and civil engineering industries. -Then reconnects elements at “nodes” as if nodes were pins or drops of glue that hold elements together.-This process results in a set of simultaneous algebraic equations. FEM: Method for numerical solution of field problems. Number of degrees-of-freedom (DOF) Continuum: Infinite FEM: Finite (This is the origin of the name, Finite Element 6.3 Finite element mesh depicting global node and element numbering, as well as global degree of freedom assignments (both degrees of freedom are ﬁxed at node 1 and the second degree of freedom is ﬁxed at node 7) . . . .

T he term FEM (Finite Element Method) has gained a lot of traction in past few decades, specially in t he field of virtual product development which involves creating mathematical models of a real system and using numerical methods to analyse its response for a variety of real load-case scenarios. FINITE ELEMENT METHOD –WHAT IS IT? The Finite Element Method (FEM) is a numerical method of solving systems of partial differential equations (PDEs) It reduces a PDE system to a system of algebraic equations that can be solved using traditional linear algebra techniques. In simple terms, FEM is a method for dividing up a very complicated problem into small elements that can be solved in relation to each other. The various branches of the DEM family are the distinct element method proposed by Peter A. Cundall in 1979, the generalized discrete element method (Williams, Hocking & Mustoe 1985), the discontinuous deformation analysis (DDA) (Shi 1992) and the finite-discrete element method concurrently developed by several groups (e.g., Munjiza and Owen).

Boundary value problems are also called field problems. The field is the domain of interest and most often represents a physical structure. 1.1 What is the ﬁnite element method The ﬁnite element method (FEM) is a numerical technique for solving problems which are described by partial differential equations or can be formulated as functional minimization. A domain of interest is represented as an assembly of ﬁnite elements . Approximating functions in ﬁnite elements are deter- Introduction I. Basic Concepts The finite element method (FEM), or finite element analysis (FEA), is based on the idea of building a complicated object with simple blocks, or, dividing a complicated object into small and manageable pieces. Application of this simple idea can be found everywhere in everyday life, as well as in engineering.

### A finite element method (abbreviated as FEM) is a numerical technique to obtain an approximate solution to a class of problems governed by elliptic partial

theory that forms the f oundation of the finite element method of analysis (FEM). The focus for this article is on beam formulations which in the author’s opinion constitute the vast majority of FEM analysis conducted by practicing structural engineers. Although the current discussions Today the finite element method (FEM) is considered as one of the well established and convenient technique for the computer solution of complex problems in different fields of engineering: civil engineering, mechanical engineering, nuclear engineering, biomedical engineering, hydrodynamics, heat conduction, geo-mechanics, etc. From other side, FEM The name "nite element method" is meant to suggest the technique we apply to all problems.
