Hello all!

In the stokes demo (taylor-hood), I notice spurious pressure spikes near 
the corners. What is causing these?

I changed to a paraboloc inflow profile (consistent with the no-slip 
BCs), but the problem remains. Further, I ran the same problem on a 
unitsquare mesh (see plot attached). The pressure spikes are large. Is 
the demo problem ill posed?

Thanks!
