outlet can be managed in terms of some free-stream condition, e.g. n.grad (u) = 0. That leads to change the source term and the coefficients of the pressure matrix.
It is quite easy to find in...

For incompressible flows, the "pressure" is not a thermodinamic function but it enforces the divergence-free velocity field by means of the Poisson equation.
Said that, BC.s for velocity and...
