Models for incompressible flows are of saddle point type and they possess a coupling between pressure and velocity variables. Pressure correction methods overcome this major difficulty -for time dependent models- by decoupling the momentum equation from the continuity equation. The common approach is:
(i) | compute a not necessarily divergence-free velocity field, |
(ii) | solve a Poisson problem for pressure and |
(iii) | project the previously computed velocity onto a divergence free one. |
