Explanation of PIMPLE algorithm

Tobi · October 21, 2014, 15:46

Hello all,

I made two blog entries to explain how the pimple algorithm is working. I hope I get everything correct and could help you to understand the things.

Blog entry 1: http://www.cfd-online.com/Forums/blo...hm-part-i.html
Blog entry 2: http://www.cfd-online.com/Forums/blo...m-part-ii.html

Hope it is helpful,
Kind regards
Tobi

Thanks for your effort Tobi, it's much clarifying and really helpful. Maybe I'm asking for too much but could you do something similar with the SIMPLE algorithm? I would really appreciate it.

Regards,

Alex

Hi Alex,

in the next days/weeks I will investigate time into the SIMPLE and PISO algorithm too. Yesterday in the evening and I had time to do it. Normally there is not much time to do something like that. At the moment I am still working on the PIMPLE blog. I updated some equations etc.

Thanks for your feedback and that it is helpful for you.

Greetings to all!

Just thought to let you know that these wiki pages exist:

@Tobi: Any chance those two blog posts could be copy-paste-adapted to openfoamwiki.net? Although, keep in mind the license the wiki uses

Hi bruno,

Of course I can insert this to the wiki. But first I will check out the hints on my blog (: and extend it to complete it.

After that I will move / copy it to the wiki. I have to look to the license (:

Hi Bruno,

done: http://openfoamwiki.net/index.php/ThePimpleAlgorithm

Hope its okay in that way.

Hi Tobi,

I didn't manage to read it properly, at least not yet, but I did a couple of adjustments:

Moved the page to here: http://openfoamwiki.net/index.php/Op...hm_in_OpenFOAM
Added to the category "Numerical methods"

This way it's easier to find this page

Namely through this page: http://openfoamwiki.net/index.php/OpenFOAM_guide

Best regards,
Bruno

your welcome to modify what every you want
