Towards the ultimate conservative difference scheme. II: Monotonicity and conservation combined in a second-order scheme. (English) Zbl 0276.65055

Summary: Fromm’s second-order scheme for integrating the linear convection equation is made monotonic through the inclusion of nonlinear feedback terms. Care is taken to keep the scheme in conservation form. When applied to a quadratic conservation law, the scheme notably yields a monotonic shock profile, with a width of only 112 mesh.
