Yes, that's exactly the way to go: chop the matrix into its smallest
components, and then build them back together into large groups.
If so then I'm
not quite sure what the equivalent class for the BlockVector would be. If
there is none, then you have two options at this point:
(1) Manually construct a new BlockVector yourself (you'd basically concatenate
blocks to form the superblocks)
(2) Author an equivalent class "BlockVectorArray". I think that this wouldn't
be too difficult, because it would essentially mimic BlockMatrixArray but
offer the functionality provided by the Vector classes. This might be a nice
addition to deal.II, so I'm happy to help you with this if you'd like to give
it a go.
That would indeed be very useful. This class has been missing for over a
decade already. (In other words, it is correct that there is no such class
currently.)
