Hi,

The problem lies a lot deeper here. The project routine solves a
Poisson's equation for the projection, but it does it in a serial
fashion. This obviously does not work when the whole mesh is no longer
available. Before that it "kind of" worked in parallel, but it is very
inefficient, of course.

You can try adapting it to do this calculation in parallel. For this
you can start from the serial code and it shouldn't be hard to
achieve. If you do so, we will be happy to help get it included into
deal.II.

Best,
Timo
