Abstract

In this presentation, we will review a class of high order weighted essentially non-oscillatory (WENO) schemes with artificial linear weights for one and two dimensional hyperbolic conservation laws. The main advantages of these schemes presented in the paper are their compactness, robustness and could maintain good convergence property for solving steady state problems. The associated optimal linear weights are independent on topological structure of meshes, can be any positive numbers with only requirement that their summation equals to one. Extensive numerical results are provided to illustrate the good performance of these new WENO schemes.
