In the step-20, the mixed finite element method is used to solve a 2D
Laplace problem, where RT and DG elements are used for the velocity and
the pressure respectively. How does it work on spaces of Pn and Pn-1
elements?
Since the velocity is a vector, the main problem becomes representing
the two components of the velocity both by Pn elements.
Jie Liu -- I don't think I quite understand your question. Are you
asking whether the program would work if one used Pn/Pn-1 elements
instead of RT/DG elements?
The short answer is that that's not going to work because Pn/Pn-1 are
triangular elements. But you could use Qn/Qn-1 elements. I think that's
what step-43 does, for example.
