Detailed Description

A boundary condition object for the advection equation using a cell-centered finite volume method.

Notes:

1. This BC kernel itself does not do any complex calculation. It gets the flux vector and Jacobian matrix from the boundary flux user object being called.
2. If a system of governing equations is being solved, the flux vector and Jacobian matrix are calculated only once for the first equation and cached for use for the rest of the equations in the system.
3. On the "left" state of the boundary face, the variable value is interpolated from the reconstructed linear polynomial in the host element, which is provided from the corresponding material kernel.
4. On the "right" state of the boundary face, the variable value should be obtained from the bc user object being called.
