Abstract In this paper, an improved finite difference on a staggered mesh for shockhydrodynamics with diffuSion controlled via flux corrected transport (SMFCT) is described' The SMFCT method is designed in Lagrangian coordinates and arbitrarymesh can be used by applying a high order remapping step' A second-order numericalconvection algorithm for calculating the mass, momentum and total energy fluxes between the Eulerian cells is presented' The methods are examined numerically with six one-dimensional Riemann problems. The results show that they are successful
