Abstract

•An efficient modified WENO scheme is proposed.•This scheme switches between the linear upwind scheme and WENO-M scheme.•A switching principle based on the identification of inflection points is used.•The switching principle is calculated more quickly and leads to higher efficiency.•The WENO-M scheme leads to higher numerical accuracy and resolution.
