Abstract

The availability of powerful and inexpensive computers coupled with advances in applied mathematics make it possible to use numerical methods to integrate virtually any of the ordinary differential equations that arise in chemical kinetics. The usual numeric algorithms for integra-tion of ordinary differential equations are often inadequate because kinetics simulations often have "stiff" differential equations. The use of implicit integration generally allows even these equations to be integrated accurately. The most practical algorithms are those which monitor truncation error. These algorithms are particularly well suited for coding using the modern standard programming languages C and C++.
