Hello,
I am new to Pointwise and trying out some simple meshes to learn.
My geometry is a fairly simple cylinder (taken from a step file).
I just convert quilts into structured domains and then extrude them.
Cell size grows from 3e-5 to 0.25 by a growth rate of 1.2.
Then I perform a normal extrusion, again from 3e-5 with 1.2 rate. However, the boundary layer mesh extrudes really weirdly, it does not follow the normal and kind of swells out.
How can I prevent this from happening? Please see the images below.



Edit: even if I add a database constraint, it ends up like this:



Thanks in advance,
Huseyin
