What is it about?
This is the PAW3 S-duct grid paper, not a multi-code scorecard. Pointwise built the standard structured and unstructured IFCPT S-duct meshes (baseline, 40-probe AIP rake, and vortex generators) for the Salt Lake City workshop. We describe how those meshes were made and then check grid independence with steady FUN3D RANS. Dropping the AIP hardware out of the CAD opens a local separation just downstream of the AIP that was not in the tunnel. The supplied grids also were not a true consistently refined family, which is why recovery vs 1/N^(2/3) is not linear.

Why is it important?
Workshop scatter is not interpretable if the grids are inconsistent and the rake is missing. This paper is the meshing postmortem that later PAW cases and the FUN3D adaptation paper are answering.
Perspectives
Written while I was at Pointwise, with Chad Winkler. Read it as “here is what we handed the community, and where those meshes fall short,” then go to 2017-4835 for the adapted-mesh follow-up.
