Before revision:  Moreover, this new scheme, dubbed as MOP-WENO-ACMk, can significantly reduce the post-shock oscillations in the simulations of the two-dimensional steady problems with strong shock waves. In this article  , we  take a closer look at  various existing mapped WENO schemes in references to obtain a general formula for their mapping functions that allows the extension of the OP criterion to all existing mapped WENO schemes .
After revision:  Our goal in this article is to address this widely concerned problem , we take a closer look at various existing mapped WENO schemes in references to obtain a general formula for their mapping functions that allows the extension of the OP criterion to all existing mapped WENO schemes .
