I thought there was a bug in the Stokes Python demo (Taylor-Hood) but it gives exactly the same results as the C++ demo (with heavy oscillations in the pressure). I think I remember that we've had this problem before and fixed it, but don't remember why. Does anyone remember?
The last time we had this problem it was due to the MeshFunction that determines the subdomains on which the boundary conditions are applied. It got messed up with the mesh re-ordering business. The result was sensitive to the order in which the MeshFunction was read in and the mesh was re-ordered.
