I Need Source Code for 2D Incompressible Flow
 

Please,

I am trying to implement the SIMPLE method of Patankar in a half staggered grid, but unfortunately, I can not find where the mistakes in my code are. I am using a central difference scheme in the convective terms. I would like to know where I can find a source code of a 2D incompressible flow implementation?

Peric code is the best for educational purpose,

you could download it from: ftp://ftp.springer.de/pub/technik/peric/peric.tar.gz

good luck

Many Thanks.

do not use central difference to start with. Use upwind first , when you get results with it, then switch to central differencing. your code probably is unstable because you are using CDS
