Nodes and nodal points - The intersection of the differnt sides of elements are called nodes. However,as interest expanded in applying the finite element method to more types of problems, the use of classical theory to describe such problems became limited and could not be applied, e.g., fluid-related problems. These theories provided the reasons why the finite element method worked well for the class of problems in which variational statements could be obtained (e.g., linear diffusion type problems). The underlying mathematical basis of the finite element method first lies with the classical Rayleigh-Ritz and variational calculus procedures. Question 7. Question4: Why should one use finite elements? - The first book on the FEM by Zienkiewicz and Chung was published in 1967. Question 5. The recent introduction of BEM and meshless methods would appear to indicate the eventual obsolescence of the FEM. About 90% of a FEM program is generic, which is fairly common among most FEM codes – they tend to use similar matrix solvers, quadrature rules, and matrix assembly procedures; I/O is usually the major difference among commercial FEM codes – some are easy, and some are not so easy to learn and use.
