- The work
- Solid and fluid sharing a boundary
- What decides it
- Wall temperature and heat flux
- Cost of being wrong
- A finding in a certification file
What Courant catches here
- 01Half-converged couplingfluid 8e−07 · solid 4e−03
A conjugate case that settled on the fluid side and never on the solid.
- 02Turbulence out of boundsω < 0 in 214 cells
Wall quantities leaving their physical range, without a warning anywhere.
- 03Mesh at the interface78° non-orthogonality
Where the two regions meet — measured again after any repair.
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.
