- 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)
