Issue in making mesh. Hyperbolic mesh generation
 

I am trying to make a 3-d structured grid. I have made the grid for the wall, its quality looks good. Now, I am trying to extrude the grid in the normal direction using hyperbolic mesh generation. But when I am trying to do that, grid quality goes very bad.
Initially, I am trying to make a hyperbolic mesh in the wall-normal direction up to some height, and after that in the remaining domain, I will try algebraic or elliptic grid generation to make a domain similar to paper.

pleas ego through the issue. It will be very helpful to me.

I am attaching the link to the .pw files. It contains my files as well as the reference file showing how I want my grid to look.
