文摘This paper briefly presents the general ideas of high order accurate weighted essentially non oscillatory (WENO) schemes, and describes the similarities and differences of the two classes of WENO schemes: finite vo lume schemes and finite difference schemes. We also briefly mention a recent development of WENO schemes, namely an adaptive approach within the finite difference framework using smooth time dependent curvilinear coordinates.
