2.3.11 Stencil diagrams: spatial centering
Figure 7:
Stencil diagrams
with different spatial centering: FTBS, FTCS, FTFS.

Figure 7 shows stencil diagrams for 3 schemes with
FT (forward-time) centering
and different spatial centerings:
-
BS: backward-space
-
CS: center-space
-
FS: forward-space
The middle panel corresponds to the FTCS scheme from Eq. (92).
