TWO DIMENSIONAL ADAPTIVE MESH REFINEMENT BASED ON FINITE DIFFERENCE WENO SCHEMES
Abstract:In this paper, we mainly apply the hybrid marking strategy within adaptive mesh refinement based on finite difference WENO method to two dimensional equations. The marking strategy can improve running speed and resolution toward discontinuity. From the numerical result in this paper we can see that the method can be used in two dimensional equations, and raise the resolution of discontinuity as well as efficiency.?
