Hi all

I'm interested in using the Sacado package in Trilinos to numerically evaluate 
the global Newton matrix for a problem in which I have have hanging nodes 
handled via standard hanging-node constraints (i.e strongly). What I would like 
to know is how hard is this to do?

I have read the warning in tut-33...
"because we would have to thread the automatic differentiation we use to 
compute the elements of the Newton matrix from the residual through the 
operations of the ConstraintMatrix class. This would be possible, but is not 
trivial, and so we choose this alternative approach."

Many thanks
Andrew
