WENO methods

Short description: Scheme used in the numerical solution of hyperbolic partial differential equations

In numerical solution of differential equations, WENO (weighted essentially non-oscillatory) methods are classes of high-resolution schemes. WENO are used in the numerical solution of hyperbolic partial differential equations. These methods were developed from ENO methods (essentially non-oscillatory). The first WENO scheme was developed by Liu, Osher and Chan in 1994.[1] In 1996, Guang-Sh and Chi-Wang Shu developed a new WENO scheme[2] called WENO-JS.[3] Nowadays, there are many WENO methods.[4]
