SIMPLE algorithm
 
i'm doing a project about solving Navier-Stokes equations by using pressure correction mehod.i use SIMPLE algorithm and MAPLE programming. Time s running out but i still unable to get the exact code.

may i know who or where can i get code sample for SIMPLE algorithm(whether in MAPLE, MATLAB, C, or C++)?

regards, mia

Re: SIMPLE algorithm
 
search for peric's codes. he has simple implimented. Just follow him. Simple is not difficult to implement.

Re: SIMPLE algorithm
 
my project is based on anderson's book(computational fluid dynamics), if you have is in pg 434(applying the pressure correction method to the solution of the incompressible, viscous flow between two parallel plates by using the SIMPLE algorithm). All are there and what i only to do is programming.

formerly i did MAPLE but i have to change to MATLAB due to supervisor's request.

I stronlgy suggest the use of C/C++ or FORTRAN, Matlab is not a suitable language for CFD development (you can use Matlab for small 1d problems), Anderson describes a 2d algorithm and you will have problems implementing this in Matlab.

What exactly do you need ? Where you have encountered problems in implementing this algorithm ?

Plz use C or C++ or F . Its fun while implementing . Best of luck . I am also implementing SIMPLE for NV .

I was in total agreement with you on this for a long time (and still am to a large extent), but the trend seems be of the speeds converging, what with Matlab's improving compiler and support for parallelization. The portability/cost argument remains in effect, though.

But that's for another thread :)

hello,

my problem is same like mia,
i am also doing project, i read the vesteeg book, also patankars book,
but i am not able to write the code, and i have little time to complete the project, i am very frustreted bcause if i have not complited my project then i will be fail in taking the degree, so please help me giving the code for SIMPLE method using pressure correction and velocity correction.

thanks

Hi everyone, I know that this post is old, but did you find the solution? or potentially willing to help me? time unfortunately is also rinning out and i have been working my ass off! most of my code is written but the pressure correction step ( i'm doing steady flow) is not converging for me!? i'd greatly appreciate any help!!

Dear Michal
Find the fortran code in my blog, i have used this code for many years.
thanks hope this will help you.
it run on the windows inel fortran system.

Hello Bro ,

Can you give me the Fortran code ? or the link address for the blog ?

Thanks

Thanks to all for reply,

But I have wrote the code in C. I have written a code for square cavity by using SIMPLE algorithm and various discretization schemes. My results are good matched with the available experimental results. I have presented it in my university.

Hello, may I have a look on your SIMPLE algorithm codes? Is it not recommended to use MATLAB for this?
