Dear Wolfgang, I think the first one does the correct thing whereas the second may not.
I think so. But in my case, when following the instructions in the first one, the linear solver does not converge at all. The second one does. Since @Markus implemented the preject_boundary_values_curl_conforming function, he may know more about it. Want to fix this in the code and the documentation? I would like to. I think I should make a comprehensive understanding first.
