- What it runs on
- Conjugate and radiative cases
- What it decides
- Wall temperature and heat flux
- Cost of being wrong
- A finding in a certification file
What it checksCriterion
- 01Coupling convergenceboth regions, same floor
The fluid side settling while the solid side has not, reported as converged.
- 02Energy balance at the wallflux closure within 1%
Heat leaving one region has to arrive in the other.
- 03Radiative and convective mixview factors sum to 1
Boundary conditions that quietly double-count or drop a path.
These are criteria, not results. Nothing here has been measured — the product is not built.
What comes back
- The cause, and the line of solver output it came from
- The change, as a diff you can reverse
- Physics checks, measured against their limits
- A record somebody else can open on a link
Targets
- chtMultiRegionFoam
- Radiation models
- Solid-side conduction
Named as intent. No adapter for any of these exists today.
Standing
Buoyant and conjugate cases on OpenFOAM's own solvers are already covered by Fluids. Thermal is the surface that adds multi-region coupling, radiation and the solid side as first-class objects rather than as another flow case.
