2.3.10 Stencil diagrams
Figure 6:
Stencil diagram.
The density
at grid point
and time-step
depends on values at the old time-step
(direct
numerical domain of dependence
,
stencil
)
(103)
This is sketched in a so-called
stencil diagram
as in Fig.

.
Looking the other way, a stencil diagram tells also which points
(104)
at the new time-step
are influenced by
(
range of influence
).
