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:

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.

You're right. I've made corrections and will put the corrected paper on my web site soon. Thank you for care reading! Maciej Matyka <A HREF="http://panoramix.ift.uni.wroc.pl/~maq/">http://panoramix.ift.uni.wroc.pl/~maq/</a>

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.

ok, fixed. thank you.
