The system sort is new threads, or recent activity, you may have the wrong sorting option selected. As I also receive emails to tell me something has been added there's no need until you've not heard for a few days. Bumping after a day isn't appreciated, and will result in a miffed support engineer.
Given how coarse your new mesh is, how big a jump in cell size over the interface and how close it is to the region of interest, then no, it's not better. Have a look at the airfoil/aerofoil tutorials (might be NACA) and see how they've been meshed. Then read up on body of influence as you've split the zone out.
