fortran code
 

I need a finite volume incompressible fluid flow 2d solver code in FORTRAN (based on simple or simpler algorithm). Where I can find ? My code is not converging and giving problem in pressure correction equation from discretized continuity equation. I am using SIMPLE algorithm.

Hello Dansys,
I am also facing the same problem. I used velocity under relaxation factor as 0.25 and pressure relaxation factor as 0.1

But my solution doesn't converge unless I take the zero pressure corrections at the boundaries equal to the pressure correction of the next node towards the domain.

You can check out the codes which accompany the Feriziger and Peric book.

There are a multitude of codes which implement SIMPLE and SIMPLEC in both 2d and
3d. They are written in FORTRAN.

Here is a link to the ftp site:

Mr. tas38,
Thank you very much, I am having problem in accessing the site. Can you kindly send the codes to my mail intishar.rahman@gmail.com? I would be very greatful.
