snappyHexMesh creates disconnected regions
Functionality to add/problem to solve
snappyHexMesh is sometimes used to create multiple regions which later on get 'connected' through e.g. cyclicAMI. This does make it impossible to detect what is a properly resolved region and what is just a dangling few cells.
Target audience
Cases with faceZones that are intersecting the geometry.
Proposal
For now have option to remove small regions. This should be expressed as a fraction of 'main' region for a given zone. @Prashant
