Slit Boundaries
There are some specialized boundary conditions that implement slits, but for all physics interfaces you can add Auxiliary Slit nodes for adding slit boundary conditions on interior boundaries. The slits disconnect the fields on either sides of slit boundaries, creating a discontinuity along the slit boundaries.
When you add a slit boundary condition, the fields on both sides of the slit need some kind of constraint. A previous set of constraints might not be sufficient after an addition of slits.
Boundary Selection
In this section, select the interior boundaries where you want to apply the slit.
