Looking for Ansys Fluent guidance (meshing questions)

Hey folks,

Posting on behalf of my partner, who's working on a project where she's using Ansys Fluent for a 2D simulation of lift and drag around an airfoil. It's her first time with Ansys and she's hit some walls, especially in the meshing step.

A bit of context on the setup:
- Airfoil: S809
- Reynolds number: 3e5
- Turbulence model: k-ω SST
- Where things are going sideways in the mesh: she initially tried a structured mesh and couldn't get it to behave. She's now weighing whether an unstructured mesh is acceptable for this case, or whether a hybrid approach with a structured boundary layer with unstructured farfield is the right call. Guidance on that tradeoff, as well as some guidance on how to set up a hybrid mesh, would be really helpful.

She's already worked through various online material, plus a fair bit of YouTube, so generic intros are probably not where the gap is. It's more in diagnosing why her specific mesh isn't behaving.

What would help most:

  1. Pointers to resources that go deeper than the standard tutorials.
  2. If anyone qualified would be open to a 1:1 call to walk through her current setup and flag mistakes, she'd be happy to pay for your time. Student budget, so nothing crazy, but a fair rate for a session or two.

Happy to share screenshots of the mesh in DMs if useful. Thanks!
