Dishing on the end of a cylinder

Hello All,

I was wondering if it is possible to create an ellipsoid to use for a boolean operation? Or perhaps someone knows of a better way to do what I am trying to do.

On the face of a cylinder I want to create a dishing effect. This means I want to have a circle of radius r with a dish depth of d essentially creating a bowl like imprint on the end of the cylinder as seen in the attached figure.

If anyone has an idea of how to do this it would be greatly appreciated. I am a new CUBIT/Trelis user.

I forgot to attach the attachement describing what I’m trying to do.

Try non-uniform scaling:

create cylinder radius 1 z 3
sphere radius 1
vol 1 move z 1.5
vol 2 scale x 0.8 y 0.8 z 0.2
subtract 2 from 1
