H. Wang et al., An ELLAM scheme for multidimensional advection-reaction equations and its optimal-order error estimate, SIAM J NUM, 38(6), 2001, pp. 1846-1885
We present an Eulerian Lagrangian localized adjoint method (ELLAM) scheme f
or initial-boundary value problems for advection-reaction partial different
ial equations in multiple space dimensions. The derived numerical scheme is
not subject to the Courant-Friedrichs-Lewy condition and generates accurat
e numerical solutions even if large time steps are used. Moreover, the sche
me naturally incorporates boundary conditions into its formulation without
any artificial out ow boundary conditions needed, and it conserves mass. An
optimal-order error estimate is proved for the scheme. Numerical experimen
ts are performed to verify the theoretical estimate.
