Dear Parinaz Design Modeler has more steps to accomplish the same effect that you can do with very few clicks in SpaceClaim.
Use Face Split and a Plane twice.
To Share Topology, you must select both bodies in the Outline then right click and select Form New Part.
Now the Shared Topology should work to make a congruent mesh. However, when I tried to mesh, it did not go well. I went back to DM and instead of split face, I used Concept Slice and sliced up the disk and the liquid body with 4 slices to make 12 pieces of liquid and 4 pieces of disc. Also, the enclosure will mesh more easily if it is also a cylinder not a box.
One improvement is to add a radial bias.
