It would be most helpful to post a minimal failing example that I can look at. We can iterate from there.

With `ProjectBdrCoefficientNormal` you're projecting the normal component of the coefficient to the boundary. `ProjectBdrCoefficient` is the right thing to use here.

Your problem is not well defined. You have to think about all other boundary conditions as well.
