18.3.2 The SIMPLEC Algorithm

The SIMPLEC algorithm follows the same steps as except that $u'\, \sum a_{nb}$ is subtracted from both sides of equation (). This leads to the term A_f/a_P being replaced with

$$\frac{A_f} {a_P - \sum_{nb} \, a_{nb} }$$ (18.31)

in both the terms in the pressure correction equation and the calculation of the velocity corrections.
