Refining mesh closer to a point


For chords closer to the centre (e.g. on the red line), I want more nodes. For chords further away from the centre (e.g. on the yellow line), I want fewer nodes. Any strategy for this while keeping the mesh conformal?

Have you already tried to first mesh the top surface with a coarse mesh and then do some refinement before you sweep from top to bottom?
