Figure 3: Comparison [278] between numerical solutions to (7.122) (left, and right labeled as
Non-strictly stable) and (7.124) (right, labeled as Strictly stable). The left panel shows that the
scheme is numerically stable but not time-stable. The right panel shows that a conservative scheme
is time-stable and considerably more accurate. Reprinted with permission from [278]; copyright by
