- pattern as per surfaceFieldValue::setFaceZoneFaces()
1. define faceId, facePatchId assuming an internal face
2. if actually a boundary face:
- get facePatchId
- ignore if emptyPolyPatch or coupledPolyPatch (neighbour side)
- get patch relative faceId
This currently seems to be the least amount of code clutter.
ENH: recover some memory my shrinking lists in fluxSummary
BUG: potentially trailing rubbish in the heatExchangerModel lists
- the final resize to length actually used was missing.
Does not affect any released versions
