COMSOL Multiphyiscs

    1. The problem statement, all variables and given/known data

    How do I set a slope-matching condition in COMSOL?


    2. Relevant equations

    u1x=u2x.

    3. The attempt at a solution

    I have used the Dirichlet BC type. I have multiplied and divided by n, the number of equations, on either side of the boundary.

    Just realized I should add this...

    I have to impose a BC on the function itself and its derivative. So I have to use a Dirichlet BC.

    If it were just the derivative, I could use a Neumann, but I have to impose both.
