Abstract:
The monotonicity of the CABARET scheme approximating quasi-linear scalar conservation
law with a convex flux is analyzed. Monotonicity conditions for this scheme are
obtained in the areas where propagation velocity of characteristics has constant sign as
well as in the areas of sonic lines, sonic bands and shock waves on which propagation
velocity of characteristics of approximated divergent equation changes sign. Test
computations are presented that illustrate these properties of the CABARET scheme.
Keywords:
CABARET finite difference scheme, scalar conservation law with convex
flux, sonic lines, monotonicity.
