High-order numerical simulation on common research model (CRM) wing/body/horizontal tail model is presented with the fifth-order WCNS scheme to assess the ability of high-order WCNS scheme on complex configuration simulation and the precision of predicating cruise drag of transonic configuration. Three grids (coarse, medium and fine) are created with software ICEM according to the gridding guidelines provided by Drag Prediction Workshop (DPW) organizing committee, and the y+ of the three grids are 1, 2/3 and 4/9. Computation and analysis on three grids are carried out to investigate the grid effect on aerodynamic characteristics, pressure distribution and the local separation bubble at the wing root trailing edge. Compared to the statistic results from DPW4 and some experimental data from NTF, the high-order numerical results show that the computational results of aerodynamic characteristics agree well with statistic data; the grid density has little influence on pressure distribution on the inboard stations, whereas it has some influence on the outboard stations; the grid density has some influence on the size of the local separation bubble at the wing root trailing edge.
