WebbGodunov methods for linear advection A simple 1-d second-order accurate finite-volume method for the linear advection equation. A choice of reconstruction is provided: Godunov (piecewise constant), piecewise linear, and piecewise parabolic (PPM). WebbThis scheme is only slightly more complex than standard predictor–corrector finite difference schemes. Preliminary numerical results are presented which show that these schemes are nonoscillatory, have good shock resolution and produce results which are competitive with those produced by more complex second order Godunov-type schemes.
