Dear all

I've been looking a bit in hp-refinement. Is there anyone also looking
into this?

hp-refinement is refinement of the mesh or the polynomial order inside
an element to obtain a more accurate solution. There is an example
called DualFormulations which calculates the same quantity from two
different equations. These quantities are then used to calculate the
error norm (u1-u2,u1-u2). The example also does some adaption from this
error norm in the postprocessing. Having read something about
hp-refinement (Scott and Brenner) I don't quite understand what the
postprocessing does that could not be understood by simply plotting
(u1-u2)/(u1+u2).

Does anybody knows who made this example, and is there anyone with an
interest in this topic?

KR, Lars
