- direct construct and reset method for creating a zero-sized (dummy)
subMesh. Has no exposed faces and no parallel synchronization
required.
- core mapping (interpolate) functionality with direct handling
of subsetting in fvMeshSubset (src/finiteVolume).
Does not use dynamicMesh topology changes
- two-step subsetting as fvMeshSubsetter (src/dynamicMesh).
Does use dynamicMesh topology changes.
This is apparently only needed by the subsetMesh application itself.
DEFEATURE: remove deprecated setLargeCellSubset() method
- was deprecated JUL-2018, now removed (see issue #951)
1) Adding subMesh capabilities to momentumError and div FOs.
- A subMesh is created from cellZones.
- The operators (div, etc) are only calculated in the subMesh.
2) Optionally, halo cells can be added to the cellZones.
3) New helper class to handle the subMesh creation and field mapping.
