Wall Treatment & y+ Advisor
Choose a sensible near-wall starting strategy from the engineering objective, available wall treatment and mesh budget. This is a structured decision aid—not a replacement for solver documentation.

WORKFLOW
Choose wall modelling before choosing first-cell height.
The correct order is modelling strategy → target y+ → first-cell estimate → prism stack → solved y+ verification. Picking an arbitrary y+ target first can produce an internally inconsistent mesh/model combination.
VERIFY THE WALL STRATEGY
A wall-treatment choice is only credible after the solved y+ field is checked.
Use the advisor to choose a starting strategy, then diagnose inconsistency between the turbulence model, prism mesh and actual near-wall solution.
