I've already done corrections to my paper (bugs removed, some more explanations about SIMPLE slgorithm, new results):

"Solution to two-dimensional Incompressible Navier-Stokes Equations with SIMPLE, SIMPLER and Vorticity-Stream Function Approaches. Driven-Lid Cavity Problem: Solution and Visualization.", Maciej Matyka , University of Linkoping, CFD Project Report #3,

It is available in a PDF for and can be downloaded directly from main page of my home page:

<a href = "http://panoramix.ift.uni.wroc.pl/~maq/en"> http://panoramix.ift.uni.wroc.pl/~maq/en </a>

Please - consider helping me (see Help Me section on main page...).

Best Regards to all CFD community, Maciej Matyka

I think you have an error on Appendix A.

You discretized du/dt = -dp/dx as u=-(Pe-P)/(dt*dx). Please forgive me if I'm wrong but it seems like it should be:

u=-dt*(Pe-P)/dx

Also, some terms in the article are in Polish, as Abstract or Figure.

No problem. Actually I believe I found another error.

On page 3 section 3.2.2 you wrote: A = -a1 + 1/Re ...

I think you wanted to write: A = a1 + 1/Re, since a1 = -term1 - term2

The convection terms should be subtracted, not added, in the momentum equation using your discretization method.

It's probably a typo since even your drivencavity code comprises this change.
