I know using topoSet and subsetMesh along the lines of the mesh/moveDynamicMesh/simpleHarmonicMotion tutorial, one can cut holes into a mesh and obtain new patches. How can something similar be achieved with a vanishing hole, i.e. can a set of internal faces be turned into two touching patches with opposite orientation?
