Composite Centered Schemes for Multidimensional Conservation Laws
Richard Liska and Burton Wendroff
The oscillations of a centered second order finite difference scheme
and the excessive diffusion of a first order centered scheme can be
overcome by global composition of the two, that is by performing cycles
consisting of several time steps of the second order method followed by
one step of the diffusive method. We show the effectiveness of this
approach on some test problems in two and three dimensions.
