A wave problem in an unbounded domain is often treated numerically by truncating the infinite domain via an artificial boundary B, imposing a so-called nonreflecting boundary condition (NRBC) on B, and then solving the problem numerically in the finite domain bounded by B. A general approach is devi

Problems of linear time-dependent dispersive waves in an unbounded domain are considered. The infinite domain is truncated via an artificial boundary B, and a high-order non-reflecting boundary condition (NRBC) is imposed on B. Then the problem is solved by a finite difference (FD) scheme in the fin
In this paper we present high-order difference schemes for convection diffusion problems. When we apply high-order numerical methods to problems where physical boundary conditions are not periodic there is a need to choose adequate numerical boundary conditions in order to preserve the high-order ac
