Principles of the Finite Element Method
The finite element method (FEM) was first used in mechanical engineering as a means of solving discrete or semi-discrete mechanical structures. Today, it is an essential tool for the solution of problems described by the partial differential equations of mathematical physics. In the following treatment we will present the FEM in relation to CAD, where it is used as a tool for the modelling of problems in various domains, such as mechanics, electromagnetics, and heat transfer.
