โฆ Synopsis
An unsplit upwind method for solving hyperbolic conservation laws in three dimensions is developed. This paper derives the algorithm by generalizing a two-dimensional advection algorithm of Van Leer and Colella to three dimensions and then making appropriate modifications. The method is implemented using the equations of gas dynamics. Several test problems are computed to both verify and display the behavior of the method. These test problems include a 1D blast wave, a 2D shock reflection off a (30^{\circ}) ramp, and a 3D astrophysical jet. (Q) 1994 Academic Press, inc.

We present and analyze the performance of a nonlinear, upwind flux split method for approximating solutions of hyperbolic conservation laws. The method is based on a new version of the single-state-approximate Riemann solver devised by Harten, Lax, and van Leer (HLL) and implemented by Einfeldt. It
