Sungick Kim is still having a problem:
Thank you very much for your replies, Anders and Johan.

Q = FunctionSpace(mesh, "DG", 1)
u1 = Function(Q)
u =  u1('-')
velocity = Expression(('u','0','0'))

As you can see above, 'u' is not a scalar but a scalar field. In this
case, how can I create an expression for the velocity vector? I intend
to use 'grad(velocity)' for later formulation.
