We construct continuum shock profiles for finite difference schemes for hyperbolic conservation laws. Our analysis is based on the time-asymptotic estimates for solutions of the difference schemes. Our result applies to dissipative schemes with the nonresonance property, such as the Lax-Friedrichs a

β¦ Synopsis
We show that the continuum shock profiles for dissipative difference schemes constructed in Part I are nonlinearly stable. It is shown first that the profiles have the conservation property, obtained as the limit of the discrete version for profiles with nearby rational, quasi-Diophantine speeds. This allows us to formulate antidifferencing of the schemes and to apply a generalization of the pointwise approach for viscous conservation laws for the stability analysis.

Discrete geometric conservation laws (DGCLs) govern the geometric parameters of numerical schemes designed for the solution of unsteady flow problems on moving grids. A DGCL requires that these geometric parameters, which include among others grid positions and velocities, be computed so that the co
