Low-cost STAR-CCM+ reproduction of DPW-7 (CRM) shows pitching moment and pitch-break onset are strongly mesh-sensitive. A 4.7M-cell AoA sweep captures global trends but predicts earlier onset; vorticity-based AMR slightly reduces drag yet degrades moment. The study clarifies cost–accuracy limits and supports faster parametric CFD workflows for aviation and other compressible-flow industries.
