WebbWe present the piecewise parabolic method, a higher-order extension of Godunov's method. There are several new features of this method which distinguish it from other higher-order Godunov-type methods. We use a higher-order spatial interpolation than previously used, which allows for a steeper representation of discontinuities, particularly ... WebbIn [1], we presented an extensive comparison of various numer.ical methods for shock hydrodynamics.
