Hello all,
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 their test functions satisfy the constraints mentioned above at the boundary) Back to the designed problem below. My question is how to set up constraints on both u and v at the boundary form Gamma_1 to Gamma_4 in the picture? Can someone give me some hints? Many thanks in advance.
