Title: | High-order methods and numerical boundary conditions | Authors: | Sousa, Ercília | Keywords: | High-order finite differences; Convection-diffusion; Boundary conditions | Issue Date: | 2007 | Citation: | Computer Methods in Applied Mechanics and Engineering. 196:45-48 (2007) 4444-4457 | Abstract: | 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 accuracy. Next to the boundary we do not usually have enough discrete points to apply the high-order scheme and therefore at these nodes we must consider different approximations, named the numerical boundary conditions. | URI: | https://hdl.handle.net/10316/4599 | DOI: | 10.1016/j.cma.2007.04.015 | Rights: | openAccess |
