Numerical methods commonly used for solving partial differential equations of the reactionadvection-diffusion type are presented. The use of implicit (e.g., Crank-Nicolson) and semiimplicit methods is emphasized as being more time-efficient than that of explicit methods. The main kinds of boundary conditions are considered. Briefly discussed are operator-splitting and spectral methods, as well as methods for equations with two spatial dimensions and for hyperbolic problems.
