Snap to a feature line on a flat surface

Does anyone know how to get SHM to split cell faces on a flat surface, in order to align with a feature line? For example, I have a simple hex mesh and want to prescribe a circular patch on one end of the mesh - see the attached.
I vaguely remember having managed it in the past (unless I am mistakenly remembering doing it in StarCCM+), but I can't for the life of me remember how, or reproduce it. Any ideas? |

Ok - the answer is to activate flag multiRegionFeatureSnap, then all is well.
(Clearly this mesh is not particulary high quality ... you'd want to extend the refinement further into the domain, but in this test case I am only interested in the fact that I have managed to split the surface faces to create a circular patch). |
