A high order accurate bound-preserving compact finite difference scheme for scalar convection diffusion equations
We show that the classical fourth order accurate compact finite difference
scheme with high order strong stability preserving time discretizations 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
