Applying Eqn. 41 to a cell-centered control volume for cell-0, one obtains the following discretized system:
|
| (45) |
where the summation is over the total number of faces defining cell-0, and 
and 
are the inviscid and viscous fluxes through face-f. 
is the volume of cell-0 and 
is the preconditioning matrix evaluated in cell-0.
