For wave phenomena in one spatial dimension, governed by hyperbolic partial di erential equations with source terms, the standard Lax-Wendro scheme leads to oscillations at discontinuous wavefronts even if the Courant-Friedrich-Lewy (CFL) number is set equal to unity. We modify the Lax-Wendro scheme
## Abstract This paper compares two formulations of LaxβWendroff TVD methods. The basis of comparison is to the results of several test problems providing both qualitative and quantitative results. Results show that using an upwind biased limiter provides higher resolution of both smooth and discon
