Hello, I am resurrecting a very old thread, here.
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. Any advice on getting this started will be much appreciated.
