Hi, all 
I have asked specific implementation of Datapostprocessor Class a week ago. 

Adding to that.. I suddenly become curious how this class take 'the first 
derivative' form the solution vector. 

For example, if I solve flow problem with Taylor hood element as step-22 
tutorial program, and take the first derivatives of the acquired solution 
velocity using Datapostprocessor Class, 
I could easily get my target quantities (derivatives) for all same dof 
points. 

However, I come up with the fact that my finite elements is only 
C0-continuous...at the vertex where two different elements meet. 
(My taylor element is degree 2 for velocity and degree 1 for pressure. )
If then, on those vertexes, how the Datapostprocessor decides which element 
to refer for the first, or second derivatives on that dof? 

Thank you

Jaekwang Kim
