How to implement the so-called transmissive boundary conditions in
step-12 tutorial,
e.g., \partial u / \partial y = 0 at top and bottom boundaries?
Houjun:
in step-12, the bilinear form is obtained by integrating by parts. Some
of the terms you obtain this way correspond to boundary integrals for
which you will want to substitute the boundary conditions above. This is
similar to the other tutorial programs in which we use Neumann boundary
conditions. There is also a substantial discussion of boundary
conditions in several of the video lectures you may want to watch.
