This is a really nice demo of the capabilities of UFL!

I also notice this:

# Re-define correct gradient
def Grad(v):
    return grad(v).T

We do the following in our NS solvers:

# Fix for transposed grad in UFL
from ufl import grad as ufl_grad
def grad(v):
    if v.rank() == 1:
        return ufl_grad(v).T
    else:
        return ufl_grad(v)

Perhaps we should take up the discussion again about the definition of
grad... :-)
