# Purpose of this case

- This case is to demonstrate the usage of `pureZoneMixture` in
    `thermophysicalProperties` file to solve for a conjugate heat transfer
    without using CHT solvers, e.g., `chtMultiRegionSimpleFoam`
- Three cellZones (zoneC inside zoneB, both zoneB and zoneC inside zoneA)
- Anisotropic conductivity is used and is oriented about edges of the box
- The box is tilted 45 deg. about Z-axis to NOT align with the anisotropic
    thermal conductivity
