摘要:We show that the classical fourth order accurate compact finite difference scheme with high order strong stability preserving time discretization for convection diffusion problems satisfies a weak monotonicity property, which implies that a simple limiter can enforce the bound preserving property without losing conservation and high order accuracy. Higher order accurate compact finite difference schemes satisfying the weak monotonicity will also be discussed.
