Dear Prof. Bangerth, Thank you for your detailed response. I understand that I need to analyse the problem some more. I am also working on visualising to get more understanding on this. Thanks for the pointers. Best regards, Vishal Subramanian -- The deal.II project is located at http

Re: [deal.II] How to set up constraints for several different variables at the boundary?

Alex, In order to handle the constraint : (v-v_s) \times n=\phi (v_f -v_s) \times n at the boundary in my research problem, I designed the following test problem to play with ConstraintsMatrix in deal.ii.  (n is the normal vector, and v, v_s, v_f are the velocities of three phases. They and
