Partial differential equations (PDEs) are used throughout science and engineering and are especially prevalent in continuum mechanics. They can be classified in much the same way as ordinary differential equations, e.g., first-order or higher-order, linear or nonlinear, homogeneous or non-homogeneous. Certain properties of PDEs are important in determining the appropriate numerical analysis for these PDEs and, because of this, those properties will be briefly reviewed here.
