Fine grained mesh control

Coreform Cubit Meshing
#1

Hi All

Quick one, I would like to create say, a hex mesh on a cylindrical anulus and I would like to have fine grained control of the number of elements radially, azimuthally and vertically. Is there an obvious way to do this, I have looked through tutorials but maybe I missed the obvious thing.

Thanks

Andy

Hi Andy,

Does the surface meshing scheme hole give you the control you are looking for?

reset
create cylin radius 2 z 2
create cyl radiu 1.5 z 2.5
subtract vol 2 from 1
curve 2 interval 40
surface 9 scheme hole rad_intervals 5 bias -1.25
mesh surface 9
mesh vol 1

Note that the sign on the bias controls the bias direction.
