摘   要:
The weighted essentially non-oscillatory (WENO) schemes are a popular class of high order numerical methods for hyperbolic partial differential equations (PDEs). While WENO schemes on structured meshes are quite mature, the development of finite volume WENO schemes on unstructured meshes is more difficult. In this talk, we will discuss a class of hybrid unstructured WENO schemes which (1) are robust on complex mesh geometries; (2) satisfy maximum principle for nonlinear scalar conservation laws; (3) preserve positivity of density and pressure for Euler equations in gas dynamics. The numerical experiments are included to demonstrate the efficiency and effectiveness of the proposed schemes.
