Two Fortran subroutines for solving generalized continuity equations using optimized Flux-Corrected Transport techniques are documented. The basic finite-difference algorithm has fourth-order accurate phases and minimum residual diffusion. Phoenical antidiffusion has been generalized to moving grids and the entire algorithm has been vectorized for efficient pipeline computation. Nonlinear coupled systems of equations and multidimensional systems can be solved by repeated application of these routines. Eulerian, sliding rezone, and Lagrangian grids are allowed, and the calculations performed in Cartesian, cylindrical, and spherical coordinate systems.
