SUMMARY

The discussion focuses on implementing a slope-matching condition in COMSOL Multiphysics, specifically using Dirichlet boundary conditions (BC). The user emphasizes the necessity of applying boundary conditions to both the function and its derivative, which rules out the use of Neumann BC. The solution involves manipulating the equations to ensure the correct application of the slope-matching condition across the boundary.

Homework Statement



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


Homework Equations



u1x=u2x.

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.
