Re: [deal.II] Obtain quadrature point value locally

Dr. Bangerth, Yes, your comment is exactly what I need, to resolve my question. I just gave a tiny adjustment on the quadrature parameter, guess what, that returned me exactly my expected data information. This is wonderful, thank you so much! I will keep up my work. Have a great weekend! Judy O

Re: [deal.II] Obtain quadrature point value locally

Judy, (1) I reset thru step-8 and step-3. Was that sufficient to make the program ready for 1-dimensional(1D) PDE? If not sufficient, I might get more coordinate returned for each quadrature point; for example, q_index = {0, 1} can be 2D coordinate for each quadrature point, that caused err

Re: [deal.II] Dirichlet bc via apply_boundary_values function

Dear Wolfgang, I am sorry for not having answered to your reply. I started using the constraints at some point and they worked well for my problem. But I came back to analyzing the issue again now. I eliminated all the coefficients, unnecessary loops and so on, as you suggested. The code has s
