ABSTRACT
Partial differential equations (PDEs) are differential equations in two or more variables, and because they involve several dimensions, solving them numerically is often computationally intensive. Moreover, they come in such a variety that they often require tailoring for individual situations. Even the same equation can have a variety of boundary conditions. Usually very little can be found out about the solutions of a PDE analytically, so they often require numerical methods. Hence, a chapter is dedicated to them.
