    The reference mesh `geom0` contains the cell-centric coordinates of the reference surface mesh with size \\( 256 \times 128 \times 3 \\), and the three channels stand
    for \\( x, y, z \\). The surface physical quantities `data.npy` are on the same reference mesh with size \\( 256 \times 128 \times 3 \\), and the three channels stand for

    The raw output of surface flow (`surf.cgns`) and 3D volume fields (`vol.cgns`) is 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.
