ABSTRACT
The solution of continuum mechanics problems, such as solid mechanics, acoustics, and heat transfer, has been made easier in the last 30 years, because of the development and computer application of two powerful numerical analysis methods. These are called the finite difference method, and the finite element method. In each of these methods, the strategy is to convert the governing differential equation within the domain where it applies into a system of simultaneous algebraic equations. These equations are solved by computer routines that are well known.
