. diffusion. Hughes and Brooks (19 82) have approached this problem within the finite elements method by the development of a single test function that reflects the speed of fluid transport (the SUPG. Rankine-Hugoniot condition (Anderson, Tannehill, and Plekher 19 84) resulting from integration by parts. While this should result in reasonable shock speed and location, discrete models. other hand the sharp resolution of the shock can be forfeited and allow for O (1) error at the transition. This is referred to as "shock-capturing," as originated by von Neumann and
