In which way are they not correct? The solution looks ok to me.

Note that I have set the boundary condition for the pressure to zero
on the entire outflow (not just a point anymore). This is intentional
(and convenient).

On the other hand, I get the following error when running the demo
with PETSc:

terminate called after throwing an instance of 'std::runtime_error'
  what():  *** Error: Cannot initialise a PETSc vector using a
  sparsity pattern.

Garth, did you just add this?
