A Discussion of Gear's Implementation of Adam's and Stiff Methods for Solving Ordinary Differential Equations.
Abstract
The report discusses the methods used in Air Force Weapons Laboratory (AFWL) subroutine DIFSUB, a subroutine design to solve a system of first order, nonlinear, ordinary differential equations (ODEs). This subroutine contains two types of methods--the methods developed C. W. Gear for solving systems of stiff equations and Adams methods for solving systems of nonstiff equations. A detailed discussion of both the Adams and stiff methods and how they are embodied in DIFSUB is presented. DIFSUB is written in FORTRAN 4 for CDC 6600 computers. Program listings are included.
