    Volumetric flow data are also provided for potential future use. We provide the cell-centric coordinates and five core flow quantities at each simulation cell, and the flow 
    quantities are in the order of density, pressure, and the velocities in the \\(x, y, z \\) directions. Since the simulation requires a large far field to implement the

    The raw input surface mesh (`wing.xyz`), output of surface flow (`surf.cgns`), and 3D volume fields (`vol.cgns`) are also available in their original formats (CGNS files with the ADF format). They need the
    CGNS library to be read out. Since they are too large, they are available via university storage upon reasonable request to the authors.
