Tetra mesh instead of sweep on simple geometry

Hi,
I have a simple geometry that I’d like to mesh into hexahedra. However, without specifying a scheme, Cubit makes a tetrahedral mesh. Why would it do this? How can I reset the default sweep scheme ?
Here is the journal file:

reset
create surface circle radius 200 xplane 
sweep surface 1  perpendicular distance 5000 
create surface circle radius 700 xplane
sweep surface 4  perpendicular distance 1200
move volume 2 x 1000 include_merged
webcut volume 2 with sheet extended from surface 2
delete volume 3 
webcut volume 1 with sheet extended from surface 9
webcut volume 1 with sheet extended from surface 8

webcut volume all with general plane x offset 3200
webcut volume all with general plane x offset 4200
imprint all
merge all
mesh vol all

Best regards,

Rocco

Hi Rocco,
in the options you can change the default element type.
Change it back to Hex/Quad. This should normally do it.
