AbstractThis paper proposes WCNSCUZ which I adapted central difference and low dissipative weights to refer concepts of WENOCU and WENO-Z. WCNSCUZ is high resolution because interpolation of this scheme is applied central stencil constructed by upwind stencils and downwind stencil. Smoothness indicator of downwind stencil is obtained from central stencil, in order to solve discontinuity stable. Moreover, interpolation of 6th order WCNSCUZ completes enough accuracy in smooth region by using low dissipative weights. 6th order showed that WCNSCUZ achieves high resolution than 7th order classical robust WCNS and can give crisp result about discontinuity. However, present study has not enough evaluation about robustness of WCNSCUZ by variable interpolation.
