I am interersted in extending the functions
vector_tools::project_boundary_values() and
vector_tools::compute_nonzero_normal_flux() or writing something similar to
extend functionality to fe_dgq and fe_dgp finite elements. I am writing here
to ask for advice about this.
My understanding is that this currently is not possible because those fe's
don't have unit support points. Is this correct? I have hacked together a
solution to get around this, but I want to clean up my code and do it
idiomatically now.
I see no reason why project_boundary_values() shouldn't already work. It
shouldn't need nodal elements. Writing a small test for it is probably the way
to go to figure out whether it already works -- making the test into one for
the testsuite would of course be even better!
As for compute_nonzero_normal_flux() -- that is more complicated. How do you
intend to make that work for non-nodal elements?
Best
W.
