What Courant catches here

  1. 01
    Half-converged coupling

    A conjugate case that settled on the fluid side and never on the solid.

    fluid 8e−07 · solid 4e−03
  2. 02
    Turbulence out of bounds

    Wall quantities leaving their physical range, without a warning anywhere.

    ω < 0 in 214 cells
  3. 03
    Mesh at the interface

    Where the two regions meet — measured again after any repair.

    78° non-orthogonality

What comes back

  • The cause, and the line of solver output it came from
  • The change, as a diff you can reverse
  • Four physics checks, measured against their limits
  • A record somebody else can open on a link

What this work is held to

  • ASME V&V 20Verification and validation in CFD and heat transfer
  • NASA-STD-7009Credibility assessment of models and simulations
  • AS9100Quality management for aerospace
  • DO-178C / DO-330Airborne software and tool qualification

Courant holds none of these certifications. It produces the verification record they ask you to keep.
