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?
