If you've used a boolean operation to cut the sphere, it will be a trimmed surface with the full original sphere surface as the underlying surface beneath the trim curves.

Currently Flow uses the full underlying surface so that is probably what was messing you up.

If you construct a half sphere using some other method than trimming (like by doing a revolve of a 90 degree arc like Pilou mentions), then you should see the result that you were probably expecting. You can also use the ShrinkTrimmedSrf command on the booleaned sphere to shrink the underlying surfaces down to the trimming boundaries.

See this previous post for some additional explanation:

In the next v3 beta Flow will automatically use only the visible area of the surface instead of the full underlying surface.

Sorry, I'm not understanding this part - what is it about a group that is not working for you? You can do flow with a group of objects, just select all the objects that you want to deform before running the command.
