What is the Difference - Coefficient and Function

Question

In the .ufl files defining solutions, I saw examples as:
function space:

RR = FiniteElement("CG", tetrahedron, 2)

and solution:

u = Coefficient(RR)

or:

u = Function(RR)

So any difference between this two?

Thanks!

Hi, according to ChangeLog Coefficient class replaced Function class way back in 2010. Those .ufl files with Function are no longer valid.
