ONERA M6 Transonic Compressible Flow

Direct Parametric MLP

The ONERA M6 swept wing develops shocks and strong surface-pressure changes in transonic flow. This case retains 18,285 nodes and 36,454 triangles from the original SU2 surface mesh.

At a fixed Mach number of 0.8395, adjust angle of attack from 2 to 4 degrees to predict three velocity components, pressure, density, temperature, specific total energy and Mach number. The frozen model passed its per-field independent comparison at 3.25 degrees.
