Similarly, moving in the backward direction, the derivatives
containing the properties at the node j+1 are evaluated at time step
n+1, while the others are evaluated at the current time step. The
following are the expressions for the constants KC1 and KC2 as
evaluated in the backward direction.
KC1 =
KC2 =
