abstract

Flux-Corrected Transport (FCT) is a conservative, monotone technique
for integrating generalized continuity and hydromagnetic equations. It
is especially useful for solving compressible-flow problems,
particularly those involving shock and rarefaction waves and contact
discontinuities. FCT accomplishes this objective by combining
integration schemes with low and high orders of spatial accuracy. The
low-order scheme provides a monotone solution, usually by the
introduction of diffusive numerical fluxes, while the high-order
scheme provides high accuracy in regions of smooth flow and shallow
gradients. The high-order solution is obtained by "antidiffusing" the
low-order, monotone solution, but only to such an extent that no new
extrema are created and no existing extrema are accentuated. This is
done by limiting, or "correcting," the antidiffusive fluxes of the
high-order scheme, hence the name Flux-Corrected Transport.
