The sequence for each iteration follows:

1. Advance to the next iteration $t = t^{n + 1}$
2. Initialise $\u^{n+1}$ and $p^{n+1}$ using latest available values of $\u$ and $p$
3. Construct the momentum equations
4. Under-relax the momentum matrix
5. Solve the momentum equations to obtain a prediction for $\u^{n+1}$
6. Construct the pressure equation
7. Solve the pressure equation for $p^{n+1}$
8. Correct the flux for $\phi^{n+1}$
9. Under-relax $p^{n+1}$
10. Correct the velocity

for $$ \u^{n+1} $$

11. If not converged, go back to step 2
