WebOct 16, 2024 · Together with the Inverse Lax–Wendroff (ILW) procedure, WENO ideas were also applied in the boundary treatment. Those methods are known for their high-resolution property, i.e., good representation of nonlinear phenomena, which is an important property in solving challenging engineering problems. WebMar 20, 2012 · For the sake of accuracy and stability, a so-called inverse Lax–Wendroff (ILW) procedure was developed. This procedure was first proposed by Goldberg and Tadmor [6], [7] for analyzing numerical boundary conditions of linear hyperbolic equations in one dimension with boundaries aligned with grid lines. WebJun 1, 2024 · The inverse Lax-Wendroff (ILW) procedure is a numerical boundary treatment technique, which allows finite difference schemes and other schemes to achieve stability and high order accuracy when using cartesian meshes to solve boundary value problems defined on complex computational domain.
