CFD Modeling with Hypermesh

Hello, 

I am new to Hypermesh and am currently trying to mesh a pipe flow as an axial symmetric plane. I created the plane by creating a surface constructed from 4 nodes and lines. I now want to refine the mesh towards one side of the plane (the wall) exponentially and thicken it towards the other (the midpoint or axis of the pipe). I am facing some difficulty in doing this as the the mesh tends to skew towards the sides. 

I would basically appreciate some guidance tutorials on how to:

1) make simple models correctly with Hypermesh (simple planes, flowfield surfaces, maybe also bulletshaped flowfields in 2D and 3D), &

2) mesh for CFD studies (which means usage of aspect ratios and gradual mesh refinement to capture boundary layer effects are important).

Could someone please recommend these? Also, I would appreciate your feedback on the problem I am facing above (what mistake am I making, or perhaps I am using the wrong features for my purpose).

With thanks & regards, 

Kuharaaj Govindan.
