Large time steps just approach the steady-state problem, which for the default EulerSolver (backward Euler) has a fixed stable solution for low Re. > I'm going to keep playing with it.

The FEMSystem stuff is working fine on my own examples, but you're right, it's as if it's just solving the steady problem on ex18. I'll check it out.
