Right. In fact, this is a question that I think I've gotten about half a dozen times this semester in my class, and so it was time again to extend the FAQs to provide an answer to your question: http://dealii.sourceforge.net/index.php/Deal.II_Questions_and_Answers#I_am_using_discontinuous_Lagrange_elements_.28FE_DGQ.29_but_they_don.27t_seem_to_have_vertex_degrees_of_freedom.21.3F Does that help you somewhat? It doesn't have an answer to do what you want to do, but for that you need to describe what you want to do first :-) W. ------------------------------------------------------------------------- Wolfgang Bangerth email: [email protected] www: http://www.math.tamu.edu/~bangerth/ _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
