Finite Element Analysis
The Finite Element Method (FEM) is one of the most effective methods for the numerical solution of field problems formulated in partial differential equations. The basic idea of the FEM is a discretization of the continuous structure into substructures. This is equivalent to replacing a domain having an infinite number of degrees of freedom by a system having a finite number of degrees of freedom. The actual continuum or structure is represented as an assembly of subdivisions called finite elements. These elements are considered to be interconnected at specified joints which are called nodes.
