Hi,
In the CFX-Solver Theory Guide Eq. 9.2 gives the PDE momentum equation. Eq. 9.5 then gives the same equation but in integral form. Why does the integral form pressure term have a subscript J? Should this be a subscript I instead as in the PDE form? Then in the discretized momentum equation Eq. 9.8 why does the pressure term not have a minus sign? Also the subscript has changed back to an I, which I think is correct. But is it? Thanks. |
