Hello! I am creating structured mesh around rather smooth air intake and find myself troubled to do it. At first sight the solution is rather obvious - triangle block with Y-topology. Unfortunately, this approach does not work because of low quality of sells at intake start point. I am not able to modify geometry in that area because it could affect flow behavior inside the intake so I need to improve quality of sell without changing of geometry. I need some tips from community of how to do this.

you have to use some innovative strategy for this.
