**Key Questions**- How can meshing guidelines be prescribed so that geometrically similar meshes are generated?
- How do we accurately, consistently, and clearly prescribe wake resolution requirements?
- What are the meshing resolution requirements and best practices/guidelines for different regions of the lift curve?
- Can a single mesh produce consistently accurate results for all angles of attack?
- What are current best practices for remeshing due to component movement?
- What roadblocks or limitations exist in our current capabilities for remeshing?
- Can RANS modeling accurately predict the influence of component movement at moderate angles of attack?
- Can RANS modeling accurately predict CLmax?
- Are steady RANS solutions guaranteed to exist for all angles of attack?
- How much error and uncertainty is associated with underconvergence of the solution residual?
- What is the effect of solution strategy (e.g. global CFL condition, global time stepping, quasi-Newton, initial conditions, etc.) on the predictions?
