How to create quadratic mesh in 3D structures?

I have some questions about meshing. In structures such as cone, cylinder and things like that, how we can make quadratic meshes?
I will attach a *.mfix file to see its example.

MFiX uses a cut-cell approach for non-rectangular geometries, where you had hexahedral mesh away from walls, and cut cells (cut cell shape and number of vertices vary) at the walls.

thank you. I got it.
