As (5.13) is normally not diagonal-dominant it
is eliminated in a pre-pass. It is important to note, that in
this case the structure of the equation system changes. The constitutive relation
for
is now given by (5.13) whereas for
by (5.14), or vice-versa. This
is accomplished by the following transformation matrix
tx, y | ![]() |
![]() |
![]() |
||
![]() |
1 | 1 |
The fluxes contained in
f can also be used to calculate
the total interface flux FI by setting up the following equation:
f![]() ![]() ![]() |
(5.15) |
with i running over all interface points.
