Boundary Condition for Baffle Faces

Hello!
I have developed a surface flow solver using the diffusive wave model form of the Saint Venant Equations. For a particular test case, I need to provide an internal face within the domain that acts as a flow controller. For creating the internal boundary, I have used the createBaffles command. On the boundary, I have specified my own gradient type boundary condition, which calculates the gradient as follows: grad(h) = A/alpha - S0 A, alpha and S0 are fields evaluated by the solver and are called within the .C file for the developed boundary condition. The problem I am facing is that the value of 'h' evaluated by the boundary condition remains confined to the left-hand side of the internal boundary. I need the 'h' value to be transferred to the right-hand side of the internal boundary. The internal boundary acts as a wall in this case, which I don't want in my case. I seek urgent suggestions regarding this. Please help. I am kind of stuck in it. |
