Selected asymptotic integration method

The second approach is a fractional-step method we call asymptotic timestep-splitting. It is developed by consideration of the specific physics of the problem being solved. Stiffness in the governing equations can be handled "asymptotically" as well as implicitly. The individual terms, including those which lead to the stiff behavior, are solved as independently and accurately as possible. Examples of such methods include the Selected Asymptotic Integration Method (4,5) for kinetics problems and the asymptotic slow flow algorithm for hydrodynamic problems where the sound speed is so fast that the pressure is essentially constant (6, 2). ... [Pg.341]

The Selected Asymptotic Integration Method (5) has been utilized for many years at NRL for the solution of the coupled "stiff" ordinary differential equations associated with reactive flow problems. This program has been optimized for the ASC. [Pg.79]
