Hi, things are working pretty much okay with the mesh refinement along the boundary; there's thing however which I wasn't able to resolve by myself. When I refine a mesh in the vicinity of the boundary of a circle, the entire circle gets refined. The lcar statement for the center point of the circle doesn't seem to be accounted for. I attached a minimal script to highlight what's going wrong (remove the last line for meshing without any refinement). Is there a canonical way to deal with this?
